摘　　要：以碳酸盐作为淋洗剂,以高锰酸钾(KMnO4)或双氧水(H2O2)为氧化剂,研究了淋洗去污修复铀污染土壤技术。实验结果表明:当碳酸根浓度为0.5 mol/L,淋洗速率为1.0 mL/min,氧化剂用量与U(IV)摩尔比为2∶1时,污染土壤中铀的去除率能够达82.4%。The method of remediation of uranium-contaminated soil was studied,using carbonate as the chemical washing reagent and potassium permanganate or peroxides as the oxidizing agent. The results suggest that the leach process,using 0. 5 M carbonate,1. 0 mL/min washing velocity,2∶1 mole ratio of oxidizing agent to uranium concentration,was able to achieve uranium removal rate of 82. 4%.
