巯基对汞特别是甲基汞有强烈的吸附作用，本试验通过对土壤添加富含巯基官能团的羊毛，初步研究含巯基物质在土壤环境中对土壤汞迁移转化作用的影响。

The serum selenium is first digested by microwave treatment and then chemically purified before analysis by using sulphydryl cotton. The optimum conditions were found to b as follows:(1) The sulphydryl cotton column is prewashed with 5 mol/L hydrochloric acid;(2) Se is desorbed by adding 1 mL of concentrated nitric acid and (3) the optimum amount of sulphydryl cotton is 0.14 g. This preconcentration step is required in order to remove matrix-interfering elements, such as Na, Mg, K and Ca.
