A REVIEW ON DESORPTION OF CADMIUM FROM ADSORBENT

Adsorption is one of the very useful technique for removal of heavy metals. Cadmium is one such heavy metal which is present in the effluent of many chemical and electrochemical industries. Adsorption of cadmium by using various low cost adsorbent is widel y studied research area. However the key to application of adsorption is regeneration and recovery of adsorbent and adsorbate respectively. Disposal of heavy metal loaded adsorbent to solid waste facilities or soil is also not very wise option. So desorption becomes important aspect of this treatment facility. Current review aims at summarizing desorption studies for cadmium desorption from used adsorbents for cadmium removal.
