      of Colocasia esculenta.

AB  -   The present study investigates the sorptive removal of Fe2+ from simulated coal 
      mine waste water using steam activated biochar (SABC) developed from the roots of 
      Colocasia 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 24 full 
      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  degrees C, 
      adsorbent dosage 1.5 g/L for a time period of 180 mins. The study suggested that 
      SABC prepared from roots of Colocasia esculenta could be used as an efficient and 
      cost effective sorbent for removal of Fe2+ from coal mine wastewater.
