Abstract

Background and Objectives:Existence arsenic in underground water puts drinking water consumers’ health at risk. Due to lack of drinking water sources in Iran, maximizing the allowable amount of arsenic is essential. The aim of this study was investigate the modified zeolite clinoptilolite with MgO arsenic for removal the arsenic from water resources.

Materials and Methods: The clinoptilolite adsorbent was modified with potassium permanganate. The examined variables in this study were equilibrium time, pH, adsorbent particle size and arsenic initial concentration. To modified adsorbent were made cation exchange capacity, external cation exchange capacity and special surface area.

Results: XRD analysis results show that adsorbent is formed from clinoptilolite 70%, 3% Ramsdellite, 8% silicon dioxide and 19% aluminum potassium. The results show that raw and modified cation exchange capacity was 5.57 and meq per gram, respectively. adsorption kinetic of arsenic on the modified absorbent will follow pseudo-second model, and suggesting that the adsorption mechanism might be a chemisorption process.

Conclusion: The finding of this study show that the MnO2-modified clinoptilolite zeolite appears to be a promising adsorbent for removing trace arsenic amounts from water.
