A mathematical model of the current density distribution in electrochemical cells / Matematički model raspodele gustine struje u elektrohemijskim ćelijama
(Serbian Chemical Society, 2011)
An approach based on the equations of electrochemical kinetics for the estimation of the current density distribution in electrochemical cells is presented. This approach was employed for a theoretical explanation of the ...
Fractal analysis of bentonite modified with heteropoly acid using nitrogen sorption and mercury intrusion porosimetry / Fraktalna analiza bentonita modifikovanog heteropoli kiselinom korišćenjem podataka sorpcione analize i živine porozimetrije
(Serbian Chemical Society, 2011)
Experimental adsorption isotherms were used to evaluate the specific surface area and the surface fractal dimensions of acid-activated bentonite samples modified with a heteropoly acid (HPW). The aim of the investigations ...
Investigation of the bioremediation potential of aerobic zymogenous microorganisms in soil for crude oil biodegradation / Ispitivanje bioremedijacionog potencijala aerobnih zimogenih mikroorganizama iz zemljišta u biodegradaciji sirove nafte
(Serbian Chemical Soc, Belgrade, 2011)
The bioremediation potential of the aerobic zymogenous microorganisms in soil (Danube alluvium, Pančevo, Serbia) for crude oil biodegradation was investigated. A mixture of paraffinic types of oils was used as the substrate. ...
Removal of aqueous phenol and phenol derivatives by immobilized potato polyphenol oxidase / Uklanjanje fenola i fenolnih derivata iz vode imobilizovanom polifenol-oksidazom iz krompira
(Serbian Chemical Soc, Belgrade, 2011)
Phenols containing halogens, which tend to deactivate the aromatic nuclei, constitute a significant category of highly toxic and difficult-to-degrade pollutants, which arise from a wide variety of industries. The main ...
Influence of chemical agents on the surface area and porosity of active carbon hollow fibers / Uticaj hemijskih agenasa na specifičnu površinu i poroznost aktivnih ugljeničnih šupljih vlakana
(Serbian Chemical Society, 2011)
Active carbon hollow fibers were prepared from regenerated polysulfone hollow fibers by chemical activation using: disodium hydrogen phosphate 2-hydrate, disodium tetraborate 10-hydrate, hydrogen peroxide, and diammonium ...
Chemical composition of white currant seed extract / Hemijski sastav ekstrakta semenki bele ribizle
(Serbian Chemical Soc, Belgrade, 2011)
From the seeds of white currant (Ribes rubrum, cv. White Champagne), a new sesquiterpenoid glycoside 1 was isolated, along with two known compounds: dihydrophaseic acid 3'-O-b-D-glucopyranoside (2), and 3-carboxymethyl-i ...
Optimization of the growth and α-amylase production of Bacillus subtilis IP 5832 in shake flask and laboratory fermenter batch cultures / Optimizacija rasta i produkcije α-amilaze Bacillus subtilis IP 5832 u šaržnim kulturama u erlenmajeru i laboratorijskom fermentoru
(Serbian Chemical Soc, Belgrade, 2011)
Cell growth and the level of α-amylase in response to the carbon and nitrogen sources used for the growth of the strain Bacillus subtilis IP 5832 were examined. Based on the amylase productivity level in shake flask cultures ...
Impact of the modification of carbon-supported, Pt-based catalysts by irreversibly adsorbed Sn, Ru and Rh on ethanol oxidation / Uticaj modifikacije platinskih nanokatalizatora ireverzibilnom adsorpcijom Sn, Ru i Rh na oksidaciju etanola
(Serbian Chemical Society, 2011)
The oxidation of ethanol was studied at Snad-, Ruad- and Rhad-modified and unmodified PtC, Pt3Sn/C and Pt3Ru2/C catalysts. Potentiodynamic, quasi-steady-state and chronoamperometric measurements were used to investtigate ...
Microwave synthesis and characterization of Pt and Pt-Rh-Sn electrocatalysts for ethanol oxidation / Mikrotalasna sinteza i karakterizacija Pt i Pt-Rh-Sn katalizatora za oksidaciju etanola
(Serbian Chemical Society, 2011)
Carbon-supported Pt and Pt-Rh-Sn catalysts were synthesized by the microwave-polyol method in ethylene glycol solution and were investigated in the ethanol electro-oxidation reaction. The catalysts were characterized in ...
Arsenic removal from aqueous solutions by sorption onto zirconium- and titanium-modified sorbents / Uklanjanje arsena iz vodenih rastvora sorpcijom na sorbentima modifikovanim cirkonijumom i titanom
(Serbian Chemical Soc, Belgrade, 2011)
Arsenic reduction in drinking water can include treatment by adsorption, switching to alternative water sources, or blending with water that has a lower arsenic concentration. Commercial sorbents MTM, Greensand and BIRM ...
