Translocation characteristics of trichloroethylene in saturated clays

Abstract

Abstract: 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.

Key words: Non-aqueous phase liquids(NAPLs), Trichloroethylene(TCE), Partition coefficient, Montmorillonoid, Kaolin, PI-MVM, multidimensional poverty measurement, poverty type, poverty degree, ecological poverty, spatial distribution
