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...

Conklin, Martha H. 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 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. These results indicated that sorption of organic compounds depends on both the properties of the compound and the organic coating. Having this information is essential for modeling cosolute transport. 1994 text Thesis-Reproduction (electronic) http://hdl.handle.net/10150/626922 http://arizona.openrepository.com/arizona/handle/10150/626922 en_US Copyright © is held by the author.
