摘　　要：为了解改性蛭石-蒙脱土在修复镉污染土壤中的作用,利用二氧化锰改性蛭石-蒙脱土,以镉富集能力较为强劲的青菜为供试品,对山西省忻州市煤矸石充填复垦区镉污染土壤进行了科学探究。实验结果可得出,二氧化锰改性后蛭石-蒙脱土可以有效修复煤矸石充填复垦区镉污染土壤。In order to understand the role of modified vermiculite montmorillonite in the remediation of cadmium contaminated soil,using manganese dioxide modified vermiculite montmorillonite,taking green vegetables with strong cadmium enrichment capacity as the test sample,a scientific study was carried out on the cadmium contaminated soil in the coal gangue filling and reclamation area of Xinzhou City,Shanxi Province.The experimental results show that vermiculite montmorillonite modified by manganese dioxide can effectively repair the cadmium contaminated soil in the reclamation area filled with coal gangue.
