REMEDIATION TECHNIQUE FOR CADMIUM CONTAMINATED GROUNDWATER: A SYSTEMATIC REVIEW

Abstract

Heavy metal pollution in soil has seriously affected the living environment of human beings Among all heavy metal pollution, cadmium (Cd) is one of the most difficult to migrate pollutants in soil. Therefore, this systematic review includes the remediation techniques of Cd-contaminated groundwater that using. Different remediation techniques, including pump and treat, permeable reactive barrier, adsorption, biosorption, electrochemical, precipitation, ion exchange and bioremediation are reviewed. The advantages and disadvantages of some remediation technologies for cadmium from groundwater are outlined in order to assist the selection of a suitable technology for a groundwater remediation project. Bioremediation is a common remediation strategy used with low Cd concentrations due to the ability of the bacterial cells to bioremediate Cd.
