Abstract

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 (H2SO4) was used to treat the adsorbent as H-zeolite and H-perlite. The capability of ion removal was preliminarily investigated from the reduction of iron in solution by X-ray fluorescence spectrometer. The result showed that treatment of adsorbents with DI water was more capability than 1M H2SO4 solution.
