Ion removal, is a long problem on natural freshwater resources. In order to modify the adsorption performance to, remove ions, from standard, iron, solution, natural zeolite and natural perlite were treated with deionized water (DI water) as D-zeolite, and, D-perlite. And, 1M sulphuric acid (H 2 SO 4) was used to treat the adsorbent as H-zeolite, and, H-perlite.
