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 lowcost to apply.
