Abstract:
   Copper ions are one of the major pollutants to human water resources. There are many techniques used for removal of heavy metals, one of the most popular removal techniques is ion exchange.
       In the present work, the removal of Cu (II) ions from aqueous solutions using a cation exchange resin in a batch stirred tank reactor was studied to get the optimum and the best conditions which give the maximum removal percent for the copper ions from the waste water.
      The resin which used in this research was supplied by Alexandria Fertilizer Company. It is strong acid; it is called LEWATIT SP 112.
       The following Parameters were studied:
i. pH
ii. Initial Cu (II) ion concentration.
iii. Rotation Speed.
iv. Temperature.
v. Solid (resin) to liquid (water which contains a certain concentration of Cu 2+) ratio.
     The study revealed the following results:
1. The suitable pH which gives maximum removal of copper is 5.
2. As initial metal ion concentration increases, the percentage removal of the Cu (II) ion adsorption decreases.
3. As rotation speed increases, the percentage removal of the Cu (II) ion adsorption increases.
4. As temperature increases, the percentage removal of the Cu (II) ion adsorption increases.
5. As the solid to liquid ratio increases, the percentage removal of the Cu (II) ion adsorption increases.
  It was found that the percentage removal of Cu2+ decreases as the number of regeneration cycle increases.
