COPPER IONS CONCENTRATION USING ION EXCHANGE RESINS

摘要

The paper present the recovery process of copper ions adsorbed onto Purolite S930 chelating resin. The recovery process was investigated using hydrochloric acid, sulfuric acid and disodium salt of ethylenediaminetetraacetic acid solutions. Experiments were carrying out using different resin dose in the range 1 - 25 g dried exhausted resin/L and varying the concentration of regeneration solution in the range 0.1 - 2 eq./L for hydrochloric and sulfuric acid, and in the range 0.1 - 0.2 eq/L for disodium salt of ethylenediaminetetraacetic acid.
