The determination of ytterbium with an ordinary polarograph is not possible in the presence of erbium. A method is worked out for quantitatively determining Yb/sup 3+/ in erbium samples by oscillographic polarography. When traces of ytterbium are determined, the sensitivity of the method is almost an order higher than that of the x-ray spectrographic analysis; the accuracy of the determinations is 11%. At concentrations of Yb/sup 3+/ higher than 0.1%, the results obtained by both methods are in good agreement. (auth)
