The Research Progress of Heavy Metal Hyperaccumulator
Phytoremediation is a technique developed in recent years to remove soil heavy metal pollution with heavy metal hyperaccumulator absorption process to accumulate environmental pollutants. The heavy metal hy-peraccumulators of As, Cd, Ni are reviewed in this paper, the mechanism and characteristics of heavy metal hyperaccumulator are explored, and the development status and development trend in future of heavy metal hy-peraccumulator are discussed also.
