Abstract: Cadmium(Cd)is a strongly toxic heavy metal that can be easily absorbed by plants and accumulated in human body through food chains so that result in health problems. Due to the increasingly wide use of cadmium and its compounds,there come more and more heavy-metal contaminated soil and other environmental problems,therefore the technologies of preventing and remedying cadmium-contaminated soil have attracted much attentions of many researchers in several fields. In this review,we introduce frequently-used remediation technologies in recent years,such as electrochemical-remediation,bioremediation,and so on,and followed a discussion about the mechanisms,applications,advantages and shortcomings of these remediation technologies. Moreover,we prospecte the future development trend of heavy-metal remediation technology,aiming at providing theory supports for the research and development of heavy metal repair.

Key words: cadmium-contaminated soil, electrochemical remediation, in situ fixation, phytoremediation, combined remediation
