Prsent studydescribe adsorption of Chromium(VI) ion on activated carbon derived from Ficusracemosabark (ACFRB)and Bombaxceiba bark (ACBCB)as a low cost adsorbent.Chromium is toxic to living being and therefore it is essential to remove it from wastewater. Adsorption capacity of activated carbon derived fromFicusracemosabark (ACFRB) and Bombaxceiba bark (ACBCB)for Cr(VI) ion abetment was investigated through batch adsorption experiments. Activated carbon was characterized using techniques like FTIR and SEM.The effects of contact time, pH and adsorbent dose on the removal of Cr(VI) have been studied and reported.The maximum adsorption capacity of the adsorbent ACBCB under study for Cr(VI) was found to be 96.8% at optimum pH 5 and 100 minutes as optimum contact time andthe percentage removal of Cr(VI) ions was found to increase with increased adsorbent doses from 1 to 6gm/lit and for adsorbent .ACFRB the maximum adsorption capacity wasfound to be 89.5% at optimum pH 5 and 120 minute asoptimum contact time The percentageremoval of Cr(VI) ions was found to increase with increased adsorbent doses from 1 to 7gm/lit.
