- Title
The effect of organic structures on pentachlorophenol adsorption on soil
- Authors
Johnson, Simon A.; Graham, Anna; Tam, Shuk-Ching
- Abstract
The adsorption of pentachlorophenol (PCP) on a soil was studied by equilibrating the soil (with and without its indigenous organic matter) with PCP in the presence and the absence of added natural organic species (benzoic acid, lactic acid, glucuronic acid and catechol). Both the added organic species and the indigenous organic matter were found to enhance PCP adsorption, the enhancement being greater with benzoic acid than with the less hydrophobic lactic acid. Adsorption of these organic species was also enhanced by PCP, suggesting the existence of a co-operative adsorption mechanism.
