英文摘要 | An investigation study has been carried out on the evolution of various impurities in submilligram quantities from thorium oxide by emission spectroscopy, without previous separation or preconcentration of these impurities. A specially perforated anode was used and this increased the precision two to three fold. It was found that a three-component carrier comprising of AgC1-BaF��-Ga�烙�� proved to be the optimum. |
