Abstract EN
The kinetics of the reduction of colloidal MnO2 by glyphosate has been investigated spectrophotometrically in an aqueous and micellar (cetyltrimethylammonium bromide, sodium lauryl sulfate) media.
The reaction follows first-order kinetics with respect to colloidal MnO2 in both the aqueous and micellar media.
The rate of oxidation increases with increase in [glyphosate] in the lower concentration range but becomes independent at its higher concentrations.
The addition of both the anionic (NaLS) and cationic (CTAB) micelles increased the rate of reduction of colloidal MnO2 by glyphosate while the nonionic TX-100 micelles did not influence the rate of reaction.
In both aqueous and micellar media, the oxidation of glyphosate occurs through its adsorption over colloidal MnO2 surface.
The reaction in micellar media was treated by considering the pseudophase model.
The values of reaction rates and binding constants in the presence of micelles were determined.
