Abstract
A new analytic kinetic-catalytic method based on catalytic effect of traces of Th(IV) on the reaction oxidation of 4-hydroxycoumarin by KMnO4 were developed and validated in this study. The linearity of the method was obtained in the range of concentrations of Th(IV) from 0.2 to 2 μg mL−1. The probable relative error is in the interval from 7.88 to 3.50% for the range of concentration of Th(IV) from 0.5 to 2 μg mL−1. Kinetic equations of investigated reactions were established. The proposed kinetic method was directly applied on determination of Th(IV) in environmental water samples. It was found that the results of Th(IV) determination in water samples obtained by proposed kinetic method and comparative atomic absorption spectrometry method were statistically agreeable.
