The process used included (a) solution of the ruthenium metal in a mixture of nitric and hydrochloric acids under pressure at 200 deg -220 deg in sealed tubes, (b) distillation of ruthenium oxide from perchloric acid solution, (c) conversion of the percbloric acid solution of rhodium to hydrochloric acid solution, (d) removal of Cu/sup 64/and Zn/sup 65/ from the chloride solution by adsorption of the zinc and copper ions on filter paper, (e) removal of K/sup 42/ by adsorption of rhodium ions on paper from perchlorate solution, and (f) recovery of the rhodium from the filter paper by solution in hydrochloric acid. This procedure resulted in a yield of 85 per cent of the total rhodium free from ruthenium, contaminants, and rhodium carrier. The time required for the separation and preparation of samples for the beta spectrometer is about 10 hr. (auth)
