Abstract

A simple and convenient voltammetric method is described for the determination of low concentration uranium in aqueous matrices. It is based on the electrochemical reduction of uranium (VI) in a complexing medium of thioglycolic acid in acetate buffer. The interference of possibly associated metal ions was examined and ruled out. It was observed that on increasing the concentration of uranium the peak current increased linearly up to a concentration of 20 ppm. Limit of determination was observed to be 0.005 ppm. The method has been successfully applied for the trace level estimation of uranium in sea water samples.
