Abstract

Cation exchange of Cu2+ ion on Na+-modified natural zeolite sampled from Cikalong West Java have been evaluated. The study was conducted by exchanging Na+ in zeolite with Cu2+ ion in solution in a batch system. Effect of the presence of Mn2+ and Ni2+ ions on exchange ability of the zeolite was also studied. Ions concentration before and after cation exchange were determined by atomic absorption spectrophotometer. Result shows that the modified natural zeolite has moderate capability in exchanging Cu2+ ion indicating good enough selectivity toward ion fed. The amount of ion exchanged is decreased in the presence of Mn2+ and Ni2+ions with no effect on zeolite’s selectivity. Na-Zeolite exchanges Cu2+ ion up to 60.36 % and 39.34 % in single solution and the presence of Mn2+ and Ni2+ ions, respectively.
