农田重金属钝化剂研究进展
Research Progress of Farmland Heavy Metal Passivant
摘要
Abstract
In situ immobilization of heavy metals in contaminated farmland is adding passivant into soil to reduce the effective concentration and bioavailability of heavy metals,thereby reduce the hazards of heavy met-als to ecological environment and soil -crop system.This method is widely used due to its characteristics of simple operation,quick effect and suitable for large -scale restoration.Different kinds of passivant have dif-ferent remediation effects and mechanisms.In this paper,the passivant was classified into three types of inor-ganic,organic and new materials,then the status of heavy metal pollution remediation was analyzed in terms of remediation mechanisms,remediation effects,affecting factors and the notices.And the composite passivant was used aiming at the combined contamination of multiple heavy metals in actual environment.It was sugges-ted that the further research should pay more attention to restoration mechanism and new passivants,and the stability of remediation effects needed to be monitored through long -term field experiment.关键词
