Competitive Adsorption and Desorption of 2,4-D and PCOC in a Volcanic Soil

Competitive Adsorption and Desorption of 2,4-D and PCOC in a Volcanic Soil

The competitive adsorption and desorption of 2,4-D and PCOC, two of the commonly used phenoxy herbicide chemicals, in a volcanic soil has been examined. A Freundlich-type isotherm incorporating competition between the solutes was used to analyze the adsorption and desorption data. The competition co...
