The complexes of copper with sodium tartrate, Trilon B and citric acid, present for example in rinsing water of galvanic industry, because of their resistance they are a challenge to extract by chemical methods, while their emission rezults in environmental and economic damages. Proposed for their extraction ion exchange was carried out with anion-exchange resins Purofine PFA600, AV-17-8 of gel type and Purolite A500, ChFO of macroporous type. At purifying of initial solutions with copper concentration of 10 mg/l under static conditions according to atomic absorption spectrometry the degree of purification 95.4-99.9% was found for all ion-exchangers. The study of equilibrium of ion exchange of named complexes from solutions with copper concentration of 10-100 mg/l by various ion exchangers has identified different types of isotherms, mostly approximated by the Langmuir and Freundlich models, and calculated parameters provide comparison of selectivity and static exchange capacity of the absorbents. Calculated limiting capacity of the macroporous ion-exchanger is reduced in row of ligands: sodium tartrate > Trilon B > citric acid; it is maximal for copper-tartrate complex for Purofine PFA600. Considering the regeneration ability studied ion-exchangers are promising for deep extraction of copper-organic complexes from dilute solutions, but need determination of dynamic and kinetic characteristics of this process.
