Optimization of Fe2+Removal from Coal Mine Wastewater using Activated Biochar ofColocasia esculenta
ABSTRACT: The present study investigates the sorptive removal of Fe2+from simulated coal mine waste water using steam activated biochar (SABC) developed from the roots ofColocasia esculenta. The process was optimized by response surface methodology (RSM) under the influence of pH, temperature, adsorbent dosage and contact time at a constant shaking speed of 180 rpm with an initial concentration of 3 mg/L. The uptake performance of the biosorbent was assessed following a 24full factorial experimental matrix developed by central composite design approach. Adsorbent was characterised by SEM, EDAX, XRD and B.E.T surface area analyzer. Maximum removal of 72.96% of Fe2+was observed at pH 7.75, temperature 37.5 °C, adsorbent dosage 1.5 g/L for a time period of 180 mins. The study suggested that SABC prepared from roots ofColocasia esculentacould be used as an efficient and cost effective sorbent for removal of Fe2+from coal mine wastewater.
