Abstract:
The situation of chromium(Cr)-contaminated soil in China is more severe. At present, it is urgent to remediate the Cr(VI)-contaminated in soil. This paper reviewed the source, remediated mechanisms, morphological transformation and toxic of Cr pollution. Based on this, many common remediated techniques of Cr-polluted soil are discussed. By analyzing the application examples and laboratory tests of various methods, the development and prospect of traditional methods, new methods and combined remediated methods and the main problem of Cr polluted soil are pointed out. In contrast, some new remediated methods and combined remediation could avoid the shortcomings of single remediation, with better remediated effect, high economic benefit and less adverse impact.
