Degradation of carbofuran and carbofuran-derivatives in presence of humic substances under basic conditions
چکیده انگلیسی

The influence of humic aggregates in water solution upon the chemical stability of carbofuran (CF) and the carbofuran-derivatives, 3-hydroxy-carbofuran (HCF) and 3-keto-carbofuran (KCF), has been investigated in basic media. An inhibition upon the basic hydrolysis of 3-hydroxy-carbofuran and 3-keto-carbofuran (∼1.7 and ∼1.5-fold, respectively) was observed and it was rationalized in terms of the micellar pseudophase model. Nevertheless, non-significant effect upon the carbofuran stability was found in the presence of humic substances. These behaviors have been compared with the corresponding ones in other synthetic colloidal aggregates.


► Influence of humic substances in stability of carbofuran and their derivatives.
► Inhibitory effects for 3-hydroxy-carbofuran and 3-keto-carbofuran were observed.
► Non-significant effect upon the carbofuran stability was found.
► These behaviors were rationalized in terms of the micellar pseudophase model.
