Abstract
The removal of Cr(VI) from aqueous solution using sulphonated black rice husk ash (SBRHA) and sulphonated white rice husk ash (SWRHA) at various pH and adsorbent doses has been studied. The uptake percentage of Cr(VI) from the solution was determined spectrophotometrically by DPC method. It was found that the amount of Cr(VI) adsorbed increases significantly with decrease in pH from 5.0 to 1.0 for SWRHA and 5.0 to 2.0 for SBRHA. The Cr(VI) adsorption increased significantly with increasing dose of the adsorbent.
