“…Thus, this paper aims at studying the sorption of these two pesticides onto a model soil sample, mainly composed of inorganic matter. Indeed, we have previously studied the sorption properties of isoproturon and dimetomorph onto a "model" sample of soil organic matter (Antoine et al 2003). We studied here the sorption as a function of the reaction time, pH, and pesticide concentration.…”

We studied the adsorption and desorption of two pesticides, namely isoproturon and dimetomorph, onto a model soil sample. We first show that the adsorption of isoproturon depends on pH, from 1 mg g 1 at pH 4 to 2 mg g 1 at pH 10, contrary to the adsorption of dimetomorph (5.8 mg g 1 ). We also studied the influence of metallic cations, copper(II), iron(III), manganese(II), and chromium(III), on the sorption of isoproturon and dimetomorph. We found that in the case of isoproturon, the presence of metallic cations does influence the retention capacity of the soil sample. The sorption becomes very weak in the presence of copper and chromium, whereas in the case of iron and manganese the sorption properties are slightly modified.
