Kinetic study of pentavalent vanadium sorption on magnetic macroporous copolymer of glycidyl methacrylate
(University of East Sarajevo, Faculty of Technology, 2021)
Chelating copolymers show high efficiency in sorption of different ionic species in aqueous
solutions. The specific structure of chelating macroporous copolymers made by the porous
matrix and functional groups with the ...
Adjsuting pH PZC value during and after adsorbent preparation
(Beograd : Institut za istraživanja i projektovanja u privredi, 2020)
Point of zero charge (PZC) is one the most valuable parameter of adsorbent preparation process, in
wastewater management. Although, this parameter may be determined measuring the electrokinetic potential (zetta
potential) ...
Alkylammonium clay based nanocomposites vs. alkylammonium- modified lignocellulosic materials in adsorption of Congo Red
(Society of Physical Chemists of Serbia, 2021)
In this study, lignocellulose waste materials and smectite clay were modified into adsorbents with surface free ammonium groups. Poplar waste biomass and brewer’s spent grain were chemically modified. Smectite based ...
