摘　　要：铀浓缩、燃料后处理与处置、核事故等可造成土壤中铀浓度的增加。江西省是我国铀矿主产区,自五十年代以来已产生大量的铀尾矿,因此,大面积受污染的土壤亟待及时治理。因纳米零价铁具有大比表面积和高吸附容量的特性,其在土壤修复领域潜力巨大。本文综述了铀污染土壤来源与现状、铀污染土壤修复方法、纳米零价铁的主要特性及其在环境和土壤修复中的应用等,可对铀污染土壤修复和治理提供参考。Uranium enriching, fuel reprocessing and disposal, nuclear accidents all contribute to increases in the concentrations of uranium in soils. Jiangxi province is one of the main production areas of uranium mines in East China, and many uranium tailings have been produced since the 1950s. Thus, widespread soils have been contaminated and need to be treated in a timely manner. Nanoscale zero - valent iron （ NZVI） displays great potential in the field of soils’ remediation due to its huge surface area, large adsorption capacity. The sources and situations of uranium-contaminated soils, the methods for remediation of uranium-contaminated soils, the main properties of NZVI and its applications in environment and soils’ remediation were reviewed. The research results can provide references for uranium contaminated soils remediation.
