چکیده
The article considers a sorption method for extracting copper ions from model nitric acid solution based on of electrolytic refining silver with using sorbents bis-picolylamine functional groups: Dowex M-4195 and AXIONIT BPA. possibility to residual concentrations in the less than 10 mg/l is shown. working capacity both samples under batch conditions, as well dynamic exchange full ?onditions (column test), are determined. effect flow rate into column kinetics BPA desorption 3 %, 5 % NH4OH was investigated, two-stage scheme tested: ammonium hydroxide
