The use in grass production of clinoptilolite as an ammonia adsorbent and a nitrogen carrier
(Srpsko hemijsko društvo, Beograd, 2015)
Clinoptilolite-rich tuff (NZ) from the Zlatokop deposit (Vranjska Banja, Serbia) was studied as a nitrogen carrier for grass production. The mechanism of binding ammonium cations present in aqueous solutions by NZ was ...
High antioxidative potential and low toxic effects of selenosemicarbazone metal complexes / Visoki antioksidativni potencijal i mali toksični efekat selenosemikarbazonskih kompleksa
(Srpsko hemijsko društvo, Beograd, 2013)
Novel metal-based compounds with therapeutic potential have become the subject of intense investigations in inorganic chemistry and biomedical science. Recently, strong dose-dependent cytotoxic activities of selenosemicarbazone ...
Structural, thermal and surface characterization of thermoplastic polyurethanes based on poly(dimethylsiloxane)
(Srpsko hemijsko društvo, Beograd, 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 ...
Aqueous extraction of anions from coal and fly ash followed by ion-chromatographic determination
(Srpsko hemijsko društvo, Beograd, 2016)
Three different techniques were applied for the aqueous extraction of anions from coal and fly ash: rotary mixer-and ultrasonic-assisted extraction with different duration time, and microwave-assisted extraction at different ...
Comparison of sequential and single extraction in order to estimate the environmental impact of metals from fly ash
(Srpsko hemijsko društvo, Beograd, 2016)
The aim of this paper is to simulate leaching of metals from fly ash in different environmental conditions using ultrasound and microwave-assisted extraction techniques. Single-agent extraction and sequential extraction ...
Ultrasound and shacking-assisted water-leaching of anions and cations from fly ash
(Srpsko hemijsko društvo, Beograd, 2016)
Two mechanical extraction techniques were used for the extraction of environmentaly interesting components of coal fly ash: shaking, during which the extraction process lasted from 6 up to 24 h, and sonication that lasted ...
Influence of bunch morphology on quality of wines produced from clones of grape variety Prokupac
(Srpsko hemijsko društvo, Beograd, 2016)
Wine quality depends mainly on the characteristics of the grape it is made of, and one of the attributes affecting wine composition is cluster and berry morphology. The aim of this study was to represent variability of the ...
Investigation of the bioremediation potential of aerobic zymogenous microorganisms in soil for crude oil biodegradation
(Srpsko hemijsko društvo, Beograd, 2011)
The bioremediation potential of the aerobic zymogenous microorganisms in soil (Danube alluvium, Pancevo, Serbia) for crude oil biodegradation was investigated. A mixture of paraffinic types of oils was used as the substrate. ...
A comparison of sample extraction procedures for the determination of inorganic anions in soil by ion chromatography / Uticaj pripreme uzorka zemljišta na određivanje neorganskih anjona metodom jonske hromatografije
(Srpsko hemijsko društvo, Beograd, 2011)
Three different extraction techniques were used for aqueous extraction of anions from soil of the type Ranker that was sampled from a serpentine site. The first technique involved the use of a rotary mixer (rotary mixer ...
Lead and silver extraction from waste cake from hydrometallurgical zinc production
(Srpsko hemijsko društvo, Beograd, 2008)
This paper presents the experimental results of the extraction of lead and silver from a lead-silver waste cake obtained in the process of hydrometallurgical zinc production. While controlling the pH value, the lead-silver ...
