摘要
镉(Cd)污染农田土壤的修复是环境质量领域关注的热点,原位钝化修复技术是一项较为经济且实用的解决方案,其技术关键在于钝化材料。本文对各类钝化材料原位钝化Cd的修复效果进行了综合比较分析,综述了钝化材料应用优劣情况、研究趋势、成本效益及其潜在修复机理,以期为Cd污染农田土壤原位钝化修复材料应用提供参考。
The remediation of cadmium(Cd)-contaminated farmland soil is the focus of the field of environmental quality.In-situ passivation remediation technology is an economical and practical solution,and its key lies in the passivation material it employs.In this study,the remediation effect of in-situ passivated Cd of various kinds of passivated materials was comprehensively analyzed;the advantages and disadvantages of its application,the research trend in this field,the cost–benefit of passivated materials,and its potential remediation mechanism were summarized,to provide a reference for the application of in-situ passivation materials for Cd-contaminated farmland soil.
