A spectrochemical method is presented for the quantitative analysis of thorium for 17 trace-impurity elements (Al, B, Be, Bi, Cd, Co, Cr, Cu, Fe, Mg, Mn, Mo, Ni, P, Pb, Si, and V). Since thorium oxide is a highly refractory material, the carrier-distillation methods are successfully applied. A mixture of 96 parts of ThO/sub 2/ and 4 parts of AgCl is arced in a deep-cratered Scribner's pedestal type electrode at 12A- As little as 0.1 ppm of cadmium and 0.05 ppm of boron can be determined. Data are also given on the sensitivity and precision for the other elements. (auth)
