%X An analysis method for the determination of rhodium in platinum-rhodium series alloy by inductively coupled plasma atomic emission spectrometry(ICP-AES) after microwave digestion was proposed.The microwave digestion conditions of sample,interference of matrix and spectral line were investigated.The results showed that the sample could be fully dissolved in a mixed acid of hydrochloric acid,hydrogen peroxide,nitric acid and hydrofluoric acid by microwave digestion twice for 60 min in closed container at 230℃.During determination of the digestion solution by ICP-AES,the interference of matrix and spectrum could be avoided by selecting proper analytical lines.The proposed method was applied to the determination of platinum-rhodium alloy simulation sample with relative error in the range of 0.10 %-0.30 % and relative standard deviation below 0.66 %(n=6),in addition the determination results were consistent with those obtained by industrial standard method.This method was applicable for the determination of rhodium in platinum-rhodium series alloy.
