Effects of operating parameters on efficiency of lead removal by complexation-microfiltration process / Uticaj radnih parametara na efikasnost uklanjanja jona olova pomoću kompleksirajuće-mikrofiltracionog procesa
(Association of Chemical Engineers of Serbia, 2012)
The majority of lead content found in the environment is a result of human activities. Heavy metals can be hazardous because they tend to bioaccumulate. A complexation-microfiltration process for the removal of Pb(II) ions ...
Enzymatic Synthesis of Aliphatic Esters of Phenolic Acids and Evaluation of Their Antioxidant Properties
(Tatranské Matliare : Slovak Society of Chemical Engineering, 2012)
The esterification activity of the commercial immobilized lipase CALB towards cinnamic acids and its derivative has been studied. Using cinnamic acid as substrate, the reaction rate constants (1.95 h-1 mM-1 for ethanol and ...
Antioxidative capacity of fermented red bean and its protein hydrolysate fractions / Antioksidativni kapacitet fermentisanog crvenog pasulja i njegovih proteinskih hidrolizata
(Društvo za ishranu Srbije, Beograd, 2012)
In this study we investigated the antioxidant activity of native and fermented red bean, or their polyphenol and peptide fractions. It was found that the antioxidant activity determined by DPPH, FRAP and TBA, significant ...
Mechanical features of copper coatings electrodeposited by the pulsating current (PC) regime on Si(111) substrate
(Electrochemical Science Group, Beograd, 2020)
Mechanical features of the Cu coatings produced by the pulsating current (PC) regime on Si(111) substrate have been investigated. The Cu coatings were electrodeposited by varying duty cycle (15-50 %) and keeping the current ...
