Abstract

An adsorptive stripping voltammetric procedure for the determination of U(VI) at an in situ plated lead film electrode is described. The U(VI) complex with cupferron was accumulated from an acetate buffer solution of pH 4.2 at the potential −0.65 V. The measurements were carried out from undeaerated solutions. The calibration graph for an accumulation time of 180 s was linear from 5 × 10−10 to 2 × 10−8 mol L−1. The detection limit was 2 × 10−10 mol L−1, the relative standard deviation for 2 × 10−8 mol L−1 U(VI) was 4.3%. The proposed procedure was validated in the course of U(VI) determination in water certified reference materials.
