Cadmium Removal from Water/Wastewater using Different Sorbents (Rewiev)

A wide range of methods has been developed for the removalof cadmium from waters and wastewaters to decrease their impact on the environment, but the removal of cadmium from water and waste water is stilla recurring challenge,especially in developing countries. Different kinds of materials such as inorganic, agriculture, biomass, and nano–synthesized are employed for removal of cadmium. Cost of materials, availability, environmental friendly, and lack of modification process to get maximum recoveries are of important parameters that highly considered to developing a method. Although, performance of thesematerialsmaynot always be optimal but theirimmediate availability often makes them attractive choices.In this paper, some important aspects of cadmium removal such as kinetic and thermodynamic theories, type and characterization of sorbents, and key parameters influencing the removal are reviewed.
