Palm Oil Fuel Ash (POFA) as an Innovative Material for Arsenic Removal from Mining Effluent

Abstract

Arsenic is toxic element, accumulate in the environment as main contaminant in aqueous waste stream. This study aimed to analyze the capability of raw palm oil fuel ash (pofa) as a potential adsorbent to remove arsenic contamination in the wastewater of mining effluent. Technology applied in this study was adsorption followed by precipitation. The maximum arsenic removal percentage of 100 % and a maximum adsorption capacity up to 0.224 mg/g was discovered. The results indicate that the method for arsenic removal from wastewater using raw pofa was effective, simple and low-cost to apply.
