URANIUM-TRACES DETERMINATION BY ADSORPTIV E STRIPPING VOLTAMETRY

A method of uranium determination in the presence of ferron by adsorpt ive stripping voltametry was proposed. The adsorption of uranium compl exes with ferron on a hanging mercury drop electrode in natural media was studied. The composition of uranium complexes with ferron was dete rminated as well as the kinetics and adsorption parameters. In a 0.1 m ole KNO3 solution (pH = 7.00 and borax buffer) the current - uranium c oncentration dependence in the presence of ferron is linear within the interval of 1.2 . 10(-8) - 3.8 . 10(-7) mole/liter after 60 sec. accu mulation time. This method was applied to establish the uranium concen tration in effluents rising from the nuclear technology.
