采用间歇吸附实验研究了我国氯碱工业周边草甸土、潮土和灰漠土对Hg（Ⅱ）的吸附/解吸特性。结果表明，氯碱厂周围3种典型土壤对Hg（Ⅱ）的吸附量由大到小依次为：草甸土（4536.24 mg/kg）、潮土（1598.62 mg/kg）、灰漠土（1272.51 mg/kg）和土壤有机质对Hg（Ⅱ）的吸附有显著影响。动力学研究表明，三种土壤对汞的吸附均具有快速阶段和缓慢阶段的特征。Hg（Ⅱ）的吸附速率以潮土最高，其次是草甸土，灰漠土最低。研究结果对干旱区土壤污染控制与治理具有指导作用，为我国西北绿洲环境汞污染研究与综合治理提供参考。
A series of batch experiments were conducted to assess the adsorption/.desorption of Hg(II) within meadow soil, fluvo-aquic soil, and gray desert.soil around the chlor-alkali industry in China. Results demonstrated that.the descending order of the adsorptive capacity of Hg(II) to the three.typical soils around a chlor-alkali plant, i.e., meadow soil (4536.24 mg/.kg), fluvo-aquic soil (1598.62 mg/kg), gray desert soil (1272.51 mg/kg),.and the soil organic matter, had a significant role in Hg(II) adsorption..Kinetic studies revealed that the Hg adsorption in the three soils was.characterized with a fast stage and a slow stage. The Hg(II) adsorption.rates are the highest for the fluvo-aquic soil, followed by the meadow.soil, and then the gray desert soil. The results will play a guiding role in.arid-zone soil pollution control and treatment, which will be a reference.for the Northwest Oasis Environmental mercury pollution studies and.integrated control in China.
