Abstract
Removal of Mg2+, Сa2+, Cu2+, Ni2+, Zn2+, Fe3+, and Pr3+ ions, tracer amounts of 137Cs, 85Sr, and 60Co radionuclides, and oxalate and ethylenediaminetetraacetate ions from solutions using a polymeric nanofiltration (NF) membrane produced by RM Nanotekh (Russia) was studied. The selectivity (S) of the NF membrane to multicharged metal cations is considerably higher than to single-charged cations. The NF membrane exhibits the highest selectivity (S = 94–97%) to triple-charged Fe3+ and Pr3+ ions and double-charged Cu2+ ions. The selectivity to double-charged Mg2+ and Zn2+ ions is somewhat lower (90–94% on the average). Among doublecharged cations, the NF membrane exhibits the lowest selectivity (80–88%) to Ni2+ and Cа2+ ions. The NF membrane shows high performance in retention of tracer amounts of Sr (S = 95%) and Co (S > 99%) radionuclides, and also of oxalate (S = 94.5%) and ethylenediaminetetraacetate (S = 97.5%) ions. Examples of using the nanofiltration method for removing 60Co from a model solution simulating NPP bottom residue and for removing transition metal impurities from a LiCl solution are presented.
