Sorption of selected heavy metals from oxalic acid solution using different types of sorbents
Original language description
Possibility of adsorption of following metals: zinc, cobalt, nickel, copper and manganese from very acidic solution of oxalic acid was observed by six different types of commercial sorbents: Purolite SST65;Lewatit MonoPlus SP112; Purolite A932; Lewatit Mono plus TP 207; Lewatit CNP80 and Dowex M4195. Metal ions were separated from the acidic solutions in batch experiments. The aqueous samples were analyzed by atomic absorption spectroscopy. Tested sorbents were compared on the basis of percentage adsorption. The best adsorption efficiencies related to the number of selected metals were achieved by Dowex M4195 with bispykolylamine functional group (Co: 72%, Ni: 75%, Cu: 86% Zn: 84%). Two of the tested sorbents had high adsorption efficiency of manganese removal (Purolite SST65: 59% and Lewatit MonoPlus SP112: 52%). We have screened several commercial resins for their suitability for metals separation at low pH. The chelating resin Dowex M-4195 appears to be the most promising. The operating conditions of sorption process were discussed in this paper.
