AbstractCadmium is biopersistant. Significant concentration of cadmium is released in the environment by various industrial activities worldwide. Therefore, removal of cadmium from waste water is now receiving greater attention from researcher various techniques for cadmium metal removal from industrial effluents has been developed. These techniques are: chemical precipitation, chemical reduction, ion exchange, evaporation, membrane processes, and adsorption. Each method has its own advantages and disadvantages among these techniques; adsorption of cadmium metal by using various materials was proved to be a very effective method. Moreover, research is needed to find the commercial and practical utility of low-cost adsorbents.From the current review, adsorption seems to be t he best alternative, help to develop new metal remediation technology and to study the scientific advances of recent years in this area.
