AB  - In the present work, a nanocomposite, based on embedding Co-doped CeO2 nanoparticles into graphitic carbon nitride (g-C3N4), was applied to functionalize commercial glassy carbon paste. This is the first application of the electrochemical sensor, developed through the proposed procedure, in electrochemical sensing. The sensor was utilized for the electrochemical determination of organophosphate pesticide fenitrothion (FNT). Cyclic voltammetry identified reversible oxidation of FNT (oxidation at 0.18 V and reduction at 0.13 V) and additional reduction at 0.62 V vs. Ag/AgCl in HCl solution (pH =1). Theoretical calculations were carried out to model and elucidate experimentally observed redox processes. Special attention was devoted to modeling experimental conditions, and based on the obtained results, a detailed redox mechanism of the investigated analyte was proposed. This represents the first complete and unambiguous elucidation of the FNT redox mechanism, supported by joined experimental and theoretical data. Square wave voltammetry (SWV) was utilized for quantification, whereby the FNT oxidation peak was chosen for monitoring the analyte concentration. The developed sensor provided a nanomolar detection limit (3.2 nmol L 1), a wide linear concentration range (from 0.01 to 13.7 μmol L 1), and good precision, repeatability, and selectivity towards FNT. Practical application possibility was explored by testing the sensor performance for examining tap water and apple samples. Recovery tests, conducted during the FNT-spiked sample assays, showed a great application capability of the developed sensor for real-time monitoring of FNT traces in environmental samples.

AB  - Herein, a screen–printed diamond electrode (SPDE) coupled with a “point-of-care” platform (30 µL-drop concepts, single-drop-detection approach) was successfully applied for the electrochemical determination of pterostilbene (PTS). Cyclic voltammetry identified irreversible oxidation of PTS, where oxidation peak was shown to be strongly dependent on the pH of the working environmental. Although the proposition of the detailed electrochemical oxidation mechanism of PTS goes out of the scope of the present research, we have determined the most probable reactive site of our analyte, by utilizing DFT-based reactivity descriptors (Fukui functions). For electrochemical quantification of PTS, oxidation peak at 0.32 V (vs. Ag/AgCl) was followed in presence of 0.5 mol L−1 of Briton–Robinson buffer solution (pH = 9). Coupled with the optimized parameters of differential pulse voltammetry (DPV), SPDE detected PTS in two linear ranges (first range was from 0.011 to 0.912 µmol L−1; second range was from 0.912 to 4.420 µmol L−1), providing the LOD and LOQ on a nanomolar level (3.1 nmol L−1 and 10.0 nmol L−1, respectively). The selectivity of the optimized DPV method was found to be excellent, with the current changes of less than 7%, in the presence of ten times higher concentrations of the certain interferences. The practical applicability of the SPDE and single-drop-detection approach in dietary supplements (with a declared PTS content of 50 mg/tablet), with the recovery values ranging from 95 to 102%, shows that the developed method has high potential for precise and accurate PTS detection, as well as exceptional miniaturization possibilities of relevant equipment for on-site sensing.

AB  - The mobility of chemical elements in the soil-orchid system has been poorly studied. The aim of this study is to evaluate the uptake and mobility of several trace (Li, Ba, Sr, Ag, Hg, and B) and macronutrients (Ca, Mg, and K) in the orchid Anacamptis morio (L.) R.M.Bateman, Pridgeon & M.W.Chase from soils in western Serbia. The sampling sites are characterized by three different bedrock types—cherts, limestones, and serpentines, which are the source of the significant chemical differences in the elemental status of the soil and plant tissues. The four-step Community Bureau of Reference sequential extraction procedure was used to determine the distribution of fractions and predict their potential phytoavailability. The orchid and soil samples were analyzed for total elemental content analysis using ICP-OES. The greatest potential for plant availability was determined for Ba and Sr, representing about 80% of the total soil content. More than 40% of Li in the soils was found to be potentially phytoavailable. Significant correlations were found between the total content of Li, B, and Sr in soils. Between 38 and 60% of Li content and more than 80% of Ba and Sr content were determined to be potentially phytoavailable by sequential analysis. The highest bioconcentration factor (> 1) was determined in the case of B and Sr for all orchid organs, while translocation factor for Li was highest in tubers and leaves. The studied elements were mainly stored in tubers and roots, indicating the exclusion strategy of A. morio as a metal tolerance mechanism. The data obtained showed significant differences in metal content in soils and plants originating from sites with different parent materials, suggesting that bedrock type and associated soil properties are important factors that determine chemical element mobility and uptake.

AB  - Based on graphene nanoplatelets capability to build block composites, as well as well-known electrochemical characteristic of the manganese oxide materials, in the present research, a nanocomposite, formed from graphene nanoplatelets (GNP) and manganese(IV)-oxide (MnO2) nanoparticles, has been proposed as a novel and convenient support for enzyme immobilization. Performance of screen printed carbon electrodes (SPCEs) was significantly improved after their modification with GNP@MnO2 (SPCE/GNP@MnO2). The polyphenolic index biosensor was prepared by applying the drop coating technique using laccase and Nafion®. Developed biosensor shows a fast and reliable amperometric response toward caffeic acid, as a model compound, at operating potential of +0.40 V (vs Ag/AgCl), with a wide linear range and detection limit of 1.9 μmol l-1. Developed procedure was successfully applied for the determination of polyphenolic indexes in wine samples. Recovery tests indicate excellent accuracy and precision of the method, concluding that the biosensor can offer a fast, accurate, reliable and precise determination of the polyphenolic index. More importantly, our results suggest a great potential for the application in real samples. © 2021 The Electrochemical Society ("ECS"). Published on behalf of ECS by IOP Publishing Limited.

AB  - L-DOPA (L-3,4-dihydroxyphenylalanine), the precursor of dopamine, is widely used in the treatment of Parkinson’s disease, thus determining and monitoring the concentration of L-DOPA is of utmost importance for both medical and scientific purposes. Although many analytical approaches, designed for drug detection and quantification, already exist, there is a constant need for modification of old and tailoring of new, faster, and selective methods. Redox active chemical species, such as L-DOPA, can be measured directly by electrochemical means, whereas electrochemical sensors combine sensitivity and selectivity within a small analytical device. This work demonstrates the development of such electrochemical sensor, based on carboxylated single-wall carbon nanotubes (SWCNT-COOH) decorated with SiO2 coated-Nd2O3 nanoparticles, and further application for the detection of L-DOPA. Developed SWCNT-COOH@Nd2O3-SiO2 sensor shows linear response in the range from 2 µmol L−1 to 52 µmol L−1 analyte concentration, and beside the low detection limit, it is characterized by a fast response time, as well as good life-time, reproducibility and repeatability.

AB  - The effects of organic versus integral and conventional crop management on content and distribution of major and trace elements in different varieties of potato were investigated in a three year field trial. A set of 48 potato tubers of four varieties with different harvesting times, cultivated in three types of agricultural systems: conventional (C), integral (I), and organic (O) were characterized based on the composition of the elements of their bulk and peel. A total of 16 elements were quantified. In order to determine the source of variation among the types of production, parts of potato and varieties, multivariate analysis of variance (MANOVA) was conducted. The results indicate that Ca, Mg, and K may be considered as important indicators of the type of production, genotypes of potato, and harvesting time. Additionally, the analyses show that ten microelements are able to distinguish between production types and genotypes of potato.

AB  - Lead isotope ratio pattern (206Pb/207Pb, 208Pb/206Pb, 206Pb/204Pb, 207Pb/204Pb, and 208Pb/204Pb) was analyzed in 59 samples of Serbian wine, from four geographical regions. By utilization of powerful inductively coupled plasma mass spectrometry (ICP-QMS), lead isotope ratios were used as unique “fingerprint”, when combined with multivariate methods of analysis (Principal Component Analysis), provided information on the geographical origin of wine. In validation of ICP- QMS method and quantitative analysis, the certified reference material NIST SRM 981 was employed to test the mass-bias correction and thallium isotopes 203Tl and 205Tl (NIST SRM 997) as an internal standard. The obtained results were discussed in correlation with the corresponding values of LIRs of different European and Australian wines. In addition, the impact of anthropogenic Pb from different sources on the total Pb isotopic composition in Serbian wines was analyzed too. On the other side, the obtained values of Pb content were compared with the applicable health safety standards, according to the International Code of Oenological Practices.

AB  - Diagnosis and treatment of some important diseased and metabolic disorders is based on successful detection of albumin. In this work, we aim to develop a simple immunosensor for the detection of human serum albumin in biological fluids. Anti-human albumin antibody was covalently attached to the activated surface of screen-printed carbon electrodes enriched with carboxyl graphene/gold nanoparticles composite. Microstructure (TEM, FE-SEM, XRD) and electrochemical (CV, EIS) characterization methods were used to investigate composite properties and to confirm the successful modification of the electrodes. Under the optimal conditions, linear working range and limit of detection were 2.5–500 μg/mL and 1.55 μg/mL, respectively. Additionally, the effect of some possibly interfering compounds was investigated and the immunosensor was used for real sample analysis. The results showed that the sensor exhibited accurate, precise and sensitive characteristics and can be promising replacement to the convention methods for albumin detection in clinical practice.

AB  - A nonenzymatic hydrogen-peroxide sensor was developed by utilization of silver nanoparticles and graphene
nanoribbons. The mentioned composite was inflicted on a screen-printed carbon electrode which provides disposable,
ready-to-use sensor. The structure and morphology of the nanocomposite were analyzed by scanning electron microscopy
and X-ray diffraction. The sensor has excellent performance toward H2O2 amperometric detection. Figures of
merit include dynamic response range from 0.05 to 5 mM and detection limit of 20 μM (at S/N =3). The fabricated
sensor was used for the determination ofH2O2 in milk samples. The obtained results showed that the proposed AgNp@

AB  - Materials held within mine tailings pose a serious risk to the environment in cases of tailings dam failure. Collapse of the tailing dam at the Stolice antimony mine in West Serbia caused a spilling of tailing slurry into the nearby river watersheds. Medium-term effects of As, Pb, Sb, Zn, and Cd from the tailings material that remained in the flooded zone 3 years after the initial exposure were evaluated. Mobility of these elements was determined by analyzing their distribution between exchangeable, reducible, oxidizable, and residual phases. Results indicate that Fe-Mn oxides represent important sinks for As, Cd, Pb, and Sb. Multivariate statistical analysis revealed that concentrations of the analyzed elements were related to sand-sized fractions, as they tended to adsorb or co-precipitate as coatings on larger particles (particularly feldspar and quartz) upon the change of redox conditions. Assessment of the most relevant physico-chemical factors, metal(loid) concentration, and mobility can be used as tool to characterize the degree of contamination of impacted sites. Percentage of sand-sized particles, content of investigated metal(loid)s, and their amount in the reducible fractions are factors determining the best remediation techniques for the area impacted by tailing spill.

AB  - The analysis of isotope ratios of lead in the mushrooms and soil, where they were grown, assisted with a principal component analysis, offered a new perspective for understanding possible chemical environment in a real setup of those compartments. The content of lead and its isotope compositions were determined in soil samples and mushroom Macrolepiota procera from unpolluted area of Mountain Goč, Serbia. Sequential extraction procedure based on the Commission of the European Community Bureau of Reference (BCR) was applied on soil samples in order to determine the distribution of lead in the labile and un-labile fractions of the soil. Caps and stipes of mushrooms were subjected to microwave acid-assisted digestion prior to measurements by inductively coupled plasma quadrupole mass spectrometer for determination of lead content and lead isotope ratios. Information about the chemical fractionation of Pb in soil, Pb isotopic data from soil fractions and fruiting bodies allowed a more detailed insight on the uptake mechanisms. Lead was predominantly associated with reducible fraction (~ 60%). Only its small portion (∼ 1%) was present in the exchangeable and acid-extractable fractions suggesting the low mobility of Pb. Lead isotope analysis revealed the presence of anthropogenic lead in the surface soil. Significant lower 206Pb/207Pb compared with other fractions was found in exchangeable and acid-soluble fraction (1.331 ± 0.010), which corresponds to the isotope ratio of European gasoline. The highest 206Pb/207Pb ratio was observed in reducible fraction (1.162 ± 0.007), while in oxidizable and residual fraction, those values were similar (1.159 ± 0.006 and 1.159 ± 0.004, respectively). Distinction of exchangeable and acid-extractable fractions from others was also confirmed, for the first time, by principal component analysis. The analysis of four isotope ratios (206Pb/207Pb, 208Pb/206Pb, 206Pb/204Pb, and 207Pb/204Pb) indicated that the analyzed M. procera accumulates lead from the first two fractions of topsoil layers.

AB  - A nanocomposite formed from graphene nanoplatelets (GNP) and manganese oxide (MnO2) nanoparticles (GNP/MnO2) was proposed as a novel and suitable support for enzyme immobilisation. The performances of screen-printed carbon electrodes (SPCEs) was highly improved after modification with GNP/MnO2 (SPCE/GNP/MnO2). The polyphenol index biosensor was prepared by surface modification of SPCE/GNP/MnO2 with drop coating of the laccase (from Trametes Versicolor) and Nafion®. All electrochemical measurements were carried out in acetate buffer, pH=4.60. The developed laccase biosensor shows fast and reliable amperometric response toward caffeic acid, as model compound, at operating potential of +0.40 V (vs. Ag/AgCl), with a linear range from 5 μmol L-1 to 2.75 mmol L-1 (r2 = 0.9997), with detection limit of 2.38 μmol L-1. Moreover, effects of possible interfering compounds were investigated. The developed procedure was successfully applied for the determination of total polyphenol content in red and white wine samples. In order to validate the proposed method, the polyphenol content in wine samples, under optimized parameters, was determined using a glassy carbon electrode. Recovery tests (95.7-97.5%) shows satisfactory accuracy and precision of the developed method, concluding that proposed construction of biosensor can offer fast, stable and reproducible determination of the polyphenol index.

AB  - In this research we demonstrated detailed electrochemistry polydatin. Polydatin is a natural compound with expressed antioxidant activity. Electrochemical behavior of polydatin was tested in the potential range from -1.5 V to 2 V at unmodified boron doped diamond electrode in various pH of supporting electrolyte. It has been noticed that polydatin provides two oxidation peaks, one at around 0.73 V and second at around 1.3 V. In the reverse scan no reduction peak was observed. Quantification of polydatin was done based on first oxidation peak using square wave voltammetry. After optimization of the method, linear working range from 1·10-7 M to 7·10-5 M was obtained, with limit of detection and limit of quantification of 6·10-9 M and 2·10-8 M, respectively. Negligible interferences effects were noticed. Developed method shows excellent accuracy and precision toward detection of polydatin. Also, developed method was used for quantification of polydatin in dietary supplements.

AB  - In present work boron doped diamond (BDD) electrode was applied for studying electrochemical behavior, as well as for quantitative determination of natural alkaloid, tubocurarine (arrow poison/ TUB). Electrochemical behavior was investigated using several organic solvents and aqueous buffers, at different pHs, as supporting electrolytes. After selection of the most appropriate supporting electrolyte and investigation of its electrochemical behavior, analytical procedures for quantitative analysis of TUB were developed in an acetonitrile/methanol (80:20) mixture and in 1 mol L−1 nitric acid, which had linear quantification ranges from 4 × 10−6 to 1 × 10−4 mol L−1 (LOD = 3.07 × 10−6 mol L−1) and 4 × 10−6 to 9 × 10−5 mol L−1 (LOD = 2.45 × 10−6 mol L−1 and 5.28 × 10−7 mol L−1, depending on the selected peak), respectively. The oxidation mechanism of TUB was proposed from the theoretical aspect. Remarkable selectivity and good sensitivity were obtained after the TUB quantification method was optimized, allowing application of the developed method for TUB quantification in biological fluids, with excellent reproducibility, accuracy and precision.

AB  - In this work, the electrochemical behaviour and the subsequent development of an analytical procedure for quantification of pesticide azamethiphos, using boron-doped diamond (BDD) electrode are reported for the first time. It was found that azamethiphos electrochemical behaviour is irreversible oxidation at the potential of around 1.70 V, in 1 M nitric acid (pH 0). Also, it was found that potential of this oxidation was not pH dependent which can be attributed to the no proton involvement in electrochemical reaction on the electrode surface. The square wave voltammetric method was most appropriate for azamethiphos quantification. Under optimised experimental conditions, linear working range from 2 to 100 mu M was estimated with the detection limit of 0.45 mu M.

abstract = "In this work, the electrochemical behaviour and the subsequent development of an analytical procedure for quantification of pesticide azamethiphos, using boron-doped diamond (BDD) electrode are reported for the first time. It was found that azamethiphos electrochemical behaviour is irreversible oxidation at the potential of around 1.70 V, in 1 M nitric acid (pH 0). Also, it was found that potential of this oxidation was not pH dependent which can be attributed to the no proton involvement in electrochemical reaction on the electrode surface. The square wave voltammetric method was most appropriate for azamethiphos quantification. Under optimised experimental conditions, linear working range from 2 to 100 mu M was estimated with the detection limit of 0.45 mu M. Negligible effect of the possible interfering compound was observed. The obtained results show that the developed analytical methodology can be an adequate replacement for the, up to date, used methods for detection of organophosphorous pesticide.",

AB  - The overall aim of this paper was to compare the multielement composition and antioxidant capacity of two Montenegrin Merlot wines obtained from specific vine clones (VCR1 and VCR 101) along with commercial Merlot wine throughout the consecutive vintages in 2010 and 2011. Elemental composition was analysed using inductively coupled plasma optical emission spectrometry (ICP-OES) and inductively coupled plasma mass spectrometry (ICP-MS). Additionally, antioxidant capacity was assessed by cyclic voltammetry. VCR 1 wine from 2011 stood out for its elemental composition. On the other hand, antioxidant capacity of VCR 101 wines was the highest one for the both vintages. According to the experimental data obtained, all three wines are good source of essential elements and products with a significant antioxidant activity and specific geographical origin.

AB  - This study aimed to describe quality and potential health benefits of three Vranac wines obtained from new grape clones (CI, CII and CIII) recently developed and recognised. In this aim, their phenolic profiles, anti-2,2-Diphenyl-1-picrylhydrazyl (DPPH) radical activities along with metal compositions were analyzed. Compared with the commercial one, CII and CIII Vranac wines were found to contain both higher contents of total phenolics, flavonoids and monomeric anthocyanins as well as anti-DPPH radical activities. The most abundant phenolics were gallic acid (8.88-16.36 mg/L), catechin (12.42-24.35 mg/L) and epicatechin (4.30-7.79 mg/L). Finally, the metal content of all the analyzed samples was within the toxicological safety limits. Taken all together, Montenegrin Vranac wines represent a rich source of both phenolics and minerals exhibiting promising antioxidant potential. CII and CIII wines can be considered for commercialising due to their high amounts of gallic acid, catechin and epicatechin, significant K/Na ratios and favourable contents of essential metals making them products with health added values.

AB  - The overall aim was to compare the quality of two Montenegrin Merlot wines obtained from new vine clones (VCR1 and VCR 101) along with commercial Merlot wine throughout the consecutive vintages in 2010 and 2011, due to preliminary screening of the potential of novel Merlot vine clones for the wine industry. The content of phenolic compounds was determined by liquid chromatography tandem mass spectrometry (LC-MS/MS). Elemental composition was analysed using inductively coupled plasma optical emission spectrometery (ICP-OES) and inductively coupled plasma mass spectrometery (ICP-MS)]. Additionaly, antioxidant capacity was assessed by cyclic voltammetry. Compared with the commercial one, both wine clones contained higher percent of major phenolic compounds (namely, gallic acid and catechin) with top values recorded for VCR1 both in 2010 (30.46 +/- 0.42 mg/1) and 2011 (28.12 +/- 0.29 mg/1). The same wines were enriched with epicatechin, resveratrol, myricetin and quercetin. Furthermore, VCR 1 wine from 2011 stood out for its elemental composition. On the other hand, antioxidant capacity of VCR 101 wines was the highest one for the both vintages. According to the experimental data obtained, both new Montenegrin Merlot wines represent good candidates for the commercialised wines with an indication of geographical origin.

AB  - Samples of the selected red wine varieties grown in Montenegro (Merlot, Cabernet Sauvignon and Vranac; vintages 2010-2012) were compared according to total phenolic content, anti-DPPH radical activity, phenolic profile and elemental composition. All the samples showed profound anti-DPPH radical activity, due to high content of total phenolic compounds (R=0.92). The most abundant phenolics were catechin and gallic acid with the highest values recorded for Merlot 2012 (43.22 and 28.65mg/L, respectively). In addition to this, the content of essential elements including the potentially toxic ones was within healthy (safe) level for all the samples analysed. This study has actually pointed out Merlot wine variety as the best quality one, though all three varieties may be used as safe and health-promoting nutritional products. [GRAPHICS] .
