摘要：

A modification of the voltammetric procedure for the determination of uranium in the presence of cupferron using hanging mercury drop electrode is presented. The pulsed potential accumulation was proposed for the minimization of interferences of surface active substances. The calibration plot for U(VI) in the presence of 2 ppm Tritonu X-100 was linear from 1.7 x 10(-10) to 2.0 x 10(-8) molL(-1) for an accumulation time of 60 s, with correlation coefficient of 0.996. The application of this method was tested in the determination of uranium in certified reference material NASS-5 and river water samples.
