Аннотация
Abstract a method of instrumental neutron activation analysis (INAA) of pure rhodium has been developed, which does not require transferring the sample into a solution to determine the elemental composition. The method allows determining about 40 impurity elements with detection limits of n×10 -5 - n×10 -9 % of mass at S r = 0.1-0.12. The method can be used to determine the microimpurity composition of ultra-pure rhodium..
