| Abstract: | According to the criterion for developing a standard sample, a standard sample for rhodium emission spectrum analysis has been prepared in our lab. The purity of the rhodium matrix was determined and the chemical composition of the impurity contents was designed based on actual needs. After adding the designed impurity elements into the Rh matrix solution, it was dried completely and then reduced with hydrogen to give the desired standard sample. The uniformity and stability were tested before the standard sample was submitted to other laboratories for validation. The results show that the standard sample meets the technical requirements, conforming to the testing requirements of GB/T 1421-2004 for rhodium powder. |
