The use of biological markers in the determination of the origin and type of organic matter in the sediments of the Tisza River
(Serbian Chemical Soc, Belgrade, 2014)
The objective of this study was to determine the origin and type of organic matter (OM) in recent sediments of the Tisza River, along a distance of 153 km through the territory of Serbia. For this purpose, group ...
The influence of pyrolysis type on shale oil generation and its composition (Upper layer of Aleksinac oil shale, Serbia)
(Serbian Chemical Soc, Belgrade, 2017)
The influence of pyrolysis type on the shale oil generation and its composition was studied. Different methods such as Rock-Eval pyrolysis, thermogravimetric analysis (TGA) and pyrolysis in the open and closed systems were ...
Synthesis, antimicrobial and antioxidative activity of some new isatin derivatives
(Serbian Chemical Society, 2014)
The isatin derivatives, Schiff bases, were synthesized by the reaction of isatin and various substituted primary amines and characterized by several spectroscopic methods. Investigation of the antimicrobial activity of the ...
Secondary metabolites of three endemic Centaurea L. species
(Serbian Chemical Soc, Belgrade, 2014)
The aerial parts of three endemic Centaurea L. species, namely C. tomorosii Micevski, C. soskae Hayek and C. galicicae Micevski, afforded the sesquiterpene lactone cnicin (1) and seven flavonoids: apigenin (2), isokaempferide ...
Structural, thermal and surface characterization of thermoplastic polyurethanes based on poly(dimethylsiloxane)
(Serbian Chemical Society, 2014)
In this study, the synthesis, structure and physical properties of two series of thermoplastic polyurethanes based on hydroxypropyl-terminated poly(dimethylsiloxane) (HP-PDMS) or hydroxyethoxypropyl-terminated poly(dimet ...
Heavy metals in Neogene sedimentary rocks as a potential geogenic hazard for sediment, soil, and surface and groundwater contamination (eastern Posavina and the Lopare Basin, Bosnia and Herzegovina)
(Serbian Chemical Soc, Belgrade, 2015)
The influence of geochemical processes (weathering, erosion and dilution) of the Internal Dinarides to the Posavina Neogene Basin and their implication to the pollution of the Sava River sediments at four sampling sites ...
Preliminary organic geochemical study of lignite from the Smederevsko Pomoravlje field (Kostolac Basin, Serbia) - Reconstruction of geological evolution and potential for rational utilization
(Serbian Chemical Soc, Belgrade, 2015)
The study was aimed at determining the origin and geological evolution of lignites from the Smederevsko Pomoravlje field (Kostolac Basin, Serbia). The possibility of a rational utilization of the coal was also considered. ...
Development and validation of a simple thin-layer chromatographic method for the analysis of p-chlorophenol in treated wastewater / Validacija tankoslojne hromatografije kao metode za jednostavno određivanje p-hlorfenola u tretiranoj otpadnoj vodi
(Serbian Chemical Soc, Belgrade, 2012)
A thin-layer chromatographic (TLC) method with densitometric detection was established for the quantification of p-chlorophenol in wastewater. Degradation efficiency of p-chlorophenol was monitored after each treatment of ...
Drmno lignite field (Kostolac Basin, Serbia): Origin and palaeoenvironmental implications from petrological and organic geochemical studies / Ligniti ležišta Drmno (basen Kostolac) - poreklo i paleouslovi stvaranja na osnovu petrografskih i organsko-geohemijskih istraživanja
(Serbian Chemical Soc, Belgrade, 2012)
The objective of the study was to determine the origin and to reconstruct the geological evolution of lignites from the Drmno field (Kostolac Basin, Serbia). For this purpose, petrological and organic geochemical analyses ...
Geochemical investigation as a tool in the determination of the potential hazard for soil contamination (Kremna Basin, Serbia)
(Belgrade : Serbian Chemical Society, 2015)
The geochemical composition of the soils and underlying sediments in the Kremna Basin was investigated. The aim was to assess whether the observed heavy metal concentrations in the soil samples represent geogenic or ...
