Effect of pH and Adsorbent Particle Size on Kinetics of Zn Removal from Aqueous Solutions Using Sepiolite and Kaolinite

Abstract

Zinc (Zn) is one of the important heavy metals that play a role in soil pollution. Clay minerals are low-cost adsorbents that can adsorb heavy metals. Therefore, this study aimed to investigate the ability of Iranian kaolinite and sepiolite to remove Zn at different pH and particle sizes. The absorption kinetics of zinc from aqueous solutions by sepiolite and kaolinite were investigated in particle sizes:
