  • 摘要: 应用Tessier与BCR（Bureau Community of Reference）形态分析方法以及固体废物浸出毒性浸出法-醋酸缓冲溶液法（HJ/T300-2007）研究了磷酸二氢钠（MSP）对土壤中铅赋存形态以及浸出浓度的影响。研究表明：Tessier法和BCR法均能证实随着磷酸二氢钠的施加，实验土壤中铅从活泼态向稳定态转化；Tessier法测定的生物活性系数（MF）值较BCR法更为保守；通过线性回归分析发现BCR法测定的MF值相关系数为0.988，优于Tessier法的相关系数0.895；Tessier法与BCR法对污染土壤中铅形态的提取均具有较高的回收率；磷酸二氢钠能有效降低实验土壤中铅的浸出浓度可达98.62%。
    Abstract: The effects of sodium dihydrogen phosphate (MSP) on lead speciation and its leaching concentration in soil were studied by Tessier, BCR sequential extraction method and Solid waste-Extraction method for leaching toxicity-acetic acid buffer solution method (HJ/T300-2007). The results of both Tessier and BCR demonstrate that the lead in the experimental soil is changed from the active state to the steady state with the application of sodium dihydrogen phosphate, and the MF value measured by Tessier method is more conservative than that of BCR. It is shown from Linear regression analysis that the MF correlation coefficient measured by BCR method was 0.988, which is better than that by Tessier method as 0.895.It also can be seen that BCR and Tessier methods have a high recovery rate of lead in the polluted soil. Lastly, it is found that sodium dihydrogen phosphate can reduce the leaching concentration of lead in soil effectively with the reduction of 98.62%.
