Abstract
ABSTRACTThe aim of the present study was to investigate the sorption and physicochemical properties of the chelating ion exchangers with bis(2-pyridylmethyl)amine and aminophosphonic functional groups before and after the sorption of galvanic wastewaters. The study was carried out on the Dowex M4195, Lewatit® MonoPlus TP 220, Purolite S 940 and Purolite S 950 ion exchangers. For the practical use of the studied ion exchangers in the process of wastewater purification, the sorption capacity of the above-mentioned ions was determined depending on the phase contact time and sorption process in the whole volume of the beads.
