Simultaneous Determination of Pb and Cd Traces in Water Samples by Anodic Stripping Voltammetry Using a Modified GC Electrode
(Wiley-Blackwell, Malden, 2011)
The determination of Pb and Cd with a Nafion-modified glassy carbon electrode and Cu-DPABA complex (Cu-DPABA NA/GCE; DPABA is methyl 3,5-bis{bis-[(pyridin-2-yl)methyl]amino}methyl-benzoate) as an alternative electrode for ...
Cold-Pressed Pumpkin Seed Oil Antioxidant Activity as Determined by a DC Polarographic Assay Based on Hydrogen Peroxide Scavenge
(Springer, New York, 2011)
Antioxidant (AO) activity of cold pressed pumpkin (Cucurbita pepo L.) seed oil, produced from three naked and one hulled variety, was assessed using a DC polarographic assay based on a hydrogen peroxide scavenge (HPS). ...
Removal of Cu2+ ions using hydrogels of chitosan, itaconic and methacrylic acid: FTIR, SEM/EDX, AFM, kinetic and equilibrium study
(Elsevier, 2011)
A removal of Cu2+ ions from aqueous solutions onto hydrogels of chitosan. itaconic and methacrylic acid has been investigated using batch adsorption technique. The extent of adsorption was investigated as a function of pH, ...
Synthesis and Characterization of Novel Urethane-Siloxane Copolymers with a High Content of PCL-PDMS-PCL Segments
(Wiley-Blackwell, Malden, 2011)
Novel polyurethane copolymers derived from 4,4'-methylenediphenyl diisocyanate (MDI), 1,4-butanediol (BD) and alpha, omega-dihydroxy-[poly(caprolactone)-poly (dimethylsiloxane)-poly(caprolactone)] (a, x-dihydroxy( ...
Isolation and identification of phenolic compounds from Hypericum richeri Vill. and their antioxidant capacity
(Taylor & Francis Ltd, Abingdon, 2011)
The chemical composition and free radical scavenging properties of the MeOH extract of Hypericum richeri and its subsequent CHCl3, n-BuOH, EtOAc and aqueous extracts were investigated. Four quercetin-3-O-glycosides, three ...
Changes of Hydrogen Peroxide and Radical-Scavenging Activity of Raspberry during Osmotic, Convective, and Freeze-Drying
(Wiley-Blackwell, Malden, 2011)
This study was conducted to investigate the influence of different drying treatments on antioxidant (AO) activity and phenolic content of raspberry (Rubus idaeus), cultivar Willamette. Whole raspberry fruits were dried ...
Assessment of the pseudo total metal content in alluvial sediments from Danube River, Serbia
(Springer, New York, 2011)
We used elemental carbon, nitrogen, hydrogen and sulfur as well as ratios of hydrogen and nitrogen with total organic carbon for investigation of source and conditions of organic matter in alluvial Danube sediments. We ...
Using the Low-Cost Waste Materials for Heavy Metals Removal from the Mine Wastewater
(Japan Inst Metals, Sendai, 2011)
The possibility of application of low-cost and easily available materials such as cardboard or sawdust for the heavy metals removal from the acid mine water was investigated. The sawdust was obtained from oak and fir-wood. ...
Grand Canonical Monte Carlo study of argon adsorption in aluminium nanopores
(Taylor & Francis Ltd, Abingdon, 2011)
We present a theoretical study of argon adsorption on a model aluminium substrate structured with cylindrical nanopores. We employ state-of-the-art computational methods to obtain (i) accurate three-dimensional adsorption ...
