Thorium forms with cupferron a precipitate of ThCup/sub 4/ in a wide pH range in the absence of strong acids and sulfates. The precipitate has a tendency to form a colloid, and it is necessary to use coagulants; the most effective is sodium chloride. Sulfosalicylic acid is a stronger masking agent than citric acid during thorium titration in the presence of rare earths. The optimum conditions were established for the amperometric titration of thorium in the presence of cerium rare earths. The method was tested with artificial mixtures. The reproducibility and the accuracy of the method are satisfactory. (auth)
