Advances in flushing agents used for remediation of heavy metal-contaminated soil

Abstract

Abstract: Soil flushing is an effective method for the remediation of soil contaminated by heavy metals,and it is an important complement to the bioremediation of contaminated soil and makes remediation of contaminated soil more systematic.Flushing agents are the key to determine the washing efficiency.This paper reviews the status and mechanism of flushing agents.The application foreground of some new flushing agents such as organic acids and biosurfactants was discussed.At the same time,the feasibility of citric acid wastewater and monosodium glutamate wastewater used for remediation of heavy metal-contaminated soils was analyzed as well.

Key words: Vicia faba, Micro-nucleus ratio, Cd²⁺, Surfactant, Acid rain
