For this reason an oscL illographic polarograph GE0KhI (Ref 7) wao used for quantitative (I)-determinations in the presence of larger quantities of tantalum (II) and impurities of iran and titanium. The potentials of the peak y,) and half peak (Pp/2 are given with respect to the saturated calom-?]. electrode. The potential difference between a 'Pcathoae and a ~attxiliary cathode was measured by means of an electron schene, i3pecially con- structod for tho mflnsur~3mojit of the equili.trium elactromotive force.

They applied a constant voltage of U. - 0.17 v and a sawtooth voltage of U- - 0.95 v. The wave of' hexavalerit uranium was clearly shown in the oscillogram (Fig.1). Fig.2 shows the oscillogram of the adsorption wave in anodic polarization (U -0-45 V, U, - 0.95 v). Fig.3 shows the change in wave height as a function of tho uranium concentration in anodic polarization. It was found that the reduction process U(VI) was irreversible to U(IV).
