Removal of arsenic using ecofriendly egg shell and black toner powder

This work is primarily focused on the study of the possible usage of ecofriendly black toner powder and egg shell powder as adsorbent material for the removal of arsenic from industrial effluent. Batch exper-iments were conducted by varying the concentration, size of the reinforcement particles, time and its pH value. The optimal pH for the effective removal of arsenic was found to be 7. The size of the particles played a significant role in removing the arsenic. Smaller size particles outperformed the bigger size par-ticles and the joint action of intra-particle transfer and pore diffusion mechanism played a major role in the removal of arsenic.
