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 ...
The effect of Ni content on passivation of copper anodes with non-standard chemical composition
(Tatranské Matliare : Slovak Society of Chemical Engineering, 2012)
In this paper are presented the results of the first appearance of full pasivation during the treatment of the waste sulphuric-acid solution generated in the conventional copper electrorefining process. The copper anodes ...
Novel membrane adsorbers incorporating cross-linked poly(glycidyl methacrylate-co-2-acrylamido-2-methylpropane sulfonic acid)
(Belgrade: Institute of Technical Sciences of SASA, 2013)
Membrane adsorption has started to replace fixed bed chromatography for separation and purification of small quantities of valuable species in biotechnology and related areas. Membrane functionalization is usually required ...
Novel negatively-charged ultrafiltration membranes made by a combination of immersion precipitation and photopolymerization
(Belgrade : Serbian Chemical Society, 2013)
Ultrafiltration (UF) membranes are currently used in industry for the concentration of proteins and other macromolecules. Performance of UF membranes is generally limited by a trade-off between permeability and selectivity ...
