On the zinc sorption by the Serbian natural clinoptilolite and the disinfecting ability and phosphate affinity of the exhausted sorbent
(Elsevier, Amsterdam, 2011)
The Serbian natural zeolite is moderately effective in removing the zinc(II) ions from aqueous solutions. At 298 K the sorption capacity varies from 13 to 26% for the initial Zn(II) solution concentration of 100 and 600 ...
The analysis of simultaneous clove/oregano and clove/thyme supercritical extraction
(Elsevier, Amsterdam, 2011)
The goal of present work was to investigate and explain kinetics and mass transfer phenomena occurring during the SFE from the mixture of two plants with different initial composition. The extractions from pure clove, ...
Hydrolysis of Penicillin G by Penicillin G Acylase Immobilized on Chitosan Microbeads in Different Reactor Systems
(Wiley-VCH Verlag Gmbh, Weinheim, 2011)
The kinetic parameters for penicillin G hydrolysis in systems with penicillin G acylase from Escherichia coli (free and immobilized on activated chitosan microbeads produced by electrostatic extrusion) were determined. The ...
A study of the removal of copper ions from aqueous solution using clinoptilolite from Serbia
(Springer, New York, 2011)
Toxic metal contamination of waste waters can be mitigated by metal adsorption to clay and zeolitic minerals, but in developing countries such environmental remediation can be cost prohibitive if these minerals are not ...
