The study of the rotating disc spectral analytical method by isotooic labelling

The rotating carbon disc spectral analytical method is frequently used for the determination of trace impurities n solutions. As a rule, noble gas atmosphere is used to reduce the matrix effects and the detection limit. The paper reports on the use of a tracer method for the examination of excitation processes. 64Cu and 99Mo solutions with and without additives were used under various excitation conditions and gas atmospheres. The activity changes yielded a number of results, having also practical mportance. (author)
