In natural environment, clay liner has been payed attention to its ability as minimizing the potential for groundwater contamination at waste disposal site. This study describes the distribution of TCE between clays and NaCl solutions in various concentration by column and batch experiments. Clay used were smectite, kaoline and their mixtures. TCE sorption isotherm show that the partition coefficients (Kd) of smectite and smectite-rich clays are approximately 3-8 times larger than those of kaoline and kaoline-rich clays. The present results suggest that clays, especially smectite, may be one of effective natural materials available for liner.
