The effect of trichloroethene on sorption of chlorinated phenols on soils and coated silica
The cosolute effect of trichloroethene (TCE) on the sorption of neutral chlorinated phenols by soils and silica coated with phenyl groups was investigated. In the coated silica system (f0e = 2% ), the sorption of the chlorinated phenol was reduced in .the presence of TCE. The proposed mechanism...

The cosolute effect of trichloroethene (TCE) on the sorption of neutral

The proposed mechanism is the competition between TCE and chlorophenols for adsorption sites. In soil systems with high organic carbon (f0e = 3.2 % ) and low organic carbon (f0e < 0.03 % ), the sorption coefficients of chlorinated phenol was not affected by the presence of TCE, indicating a partitioning mechanism.
