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