Efficiency of sea shells and crab ahells waste as eco-friendly adsorbent for treating acid rock drainage

Abstract

Acid rock drainage is a major environmental problem but also many of the availability of a vast array of remediation techniques and technologies. The current study aims to apply crushed sea shells and crab shell as an efficient and cost effective adsorption medium for acid rock drainage treatment in batch studies. The effects of adsorbent mass and solution pH were investigated in batch studies whilst initial concentration. The preliminary results showed that sea shell and crab shell derived adsorbent has a great potential as an alternative material in the treatment of acid rock drainage compared to limestone.
