【Abstract】 In-situ passivation of heavy metals is a technology for remediation of farmland soil pollution. It adds passivation material to the contaminated soil, to reduce effective concentration of heavy metals in the soil or change its redox state. This paper summarized the passiv?ation materials and its passivation mechanism for in-situ passivation repaired technology, and discussed the influencing factor for passivated effect of passivation materials on heavy metal contaminated farmland. In addition, This paper analyzed and forecasted the problems for mar?ket development of passivation materials and repairing farmland that need to be solved in the futureare, so as to provide theoretical basis and research direction for in-situ passivation repaired technology and passivation materials.更多还原
