COPPER IONS CONCENTRATION USING ION EXCHANGE RESINS

Petru BULAI, Camelia POPA

Abstract

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.
