In order to modify the adsorption performance to remove ions from synthetic 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. © 2020 Trans Tech Publications Ltd, Switzerland.AdsorptionIron ions removalPerliteWastewater treatmentZeoliteConference paperScopus
