Abstract:
Adsorption of parathion by pretreated attapulgites was studied in both organic and aqueous media. In organic media the presence of hygroscopic moisture resulted in competition between parathion and water so that an increase in the clay's moisture content reduced parathion adsorption. Heating the clays above 250 °C resulted in structural changes that cause a decrease in parathion adsorption. Adsorption of parathion in aqueous solution was found to be inversely related to the release of parathion from highly loaded clays under equilibrium conditions. Saturating clays with an organocation altered their properties favoring increased adsorption and decreased desorption. The results indicate that pretreatment of the clay might affect both the rate and amount of release to the external environment. © 1978 American Chemical Society.
