A practical method for the separation and amperometric determination of thorium in monazite sands is proposed. The attack is carried out with sulfuric acid on 10-gram samples; thorium and the rare earths are separated by a single precipitation with oxalic acid, and the final amperometric titration is made with ammonium paramolybdate as titrant. The composition of the thorium molybdate precipitated, as a function of the initial concentration of thorium, is verified. Possible interferences of some impurities that frequently occur in these sands are determined. The results agree with those of the iodate chemical method and other more laborious amperometric techniques. (auth)
