摘要
利用土柱模型以及吸附实验，分析不同ＮａＣｌ浓度情况下，三氯乙烯（ＴＣＥ）在蒙脱土和高岭土中的迁移特性．从实验中得到的等温吸附曲线表明，ＴＣＥ在蒙脱土中的吸附分配系数比在高岭土中的分配系数大３～８倍．由此可认为蒙脱上是一种可用于环境治理的天然材料．
The translocation characteristics of trichloroethylene(TCE)in saturated montmorillonoid and kaolin at different concentrations of NaCl are studied with column and batch experiments.The sorption isotherm shows that the partition coefficients(Kd)of TCE in montmorillonoid-rich clays are approximately 3￣8 times larger than those in kaolin-rich clays.It is considered that montmorillonoid is an effective natural material available for environmental management.
