| Abstract: | 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. |
