Removal of heavy metal ions from Industrial effluents using low cost Adsorbents in packed bed column

Abstract

The present work researches the removal of Cu and Cd ions using mixed adsorbent prepared by blending activated charcoal and bone charcoal in 1:1 ratio for both batch and continuous flow operation. The adsorption mechanism follows a hemisorption process due to the synergistic effect associated by contribution of high surface area from the activated charcoal (1600 m2/g) and negative charge from the bone charcoal. The potential capacity of the mixed adsorbent material for the removal of Cu (II) and Cd (II) from the newlineprepared synthetic metal ion solution was studied by optimizing various parameters in the batch study and these optimized parameters are used in the continuous flow operation to find the effect of adsorbent dose and volumetric flow rate at a constant initial metal ion newlineconcentration of 100 ppm. The batch adsorption studies has been carried out for 2 hrs considering all the 6 parameters by optimizing each of them. newline
