低温热解法修复前后土壤汞形态研究

Study on the Mercury Forms in Soils Before and After the Remediation by Using Low Temperature Pyrolysis Method

对采取低温热解法进行汞重污染土壤修复前后土壤的汞的形态进行了探索,结果表明:热解前土壤汞形态以难氧化有机结合态和残渣态为主;热解后,土壤中残留的汞中大部分都为残渣态。

This article explores the changes of the mercury forms before and after the remediation of mercury-- contaminated soils by using low temperature pyrolysis method. Before the pyrolysis, the organic--bound and residual are the major forms in the soil. After the pyrolysis, the residue is the major form of the rest mercury in the soil.
