A method is suggested for determination of Rh and Ir. It is based on using dithioacetamide as preciptating agent for preconcentration of Rh and Ir. In a solution of dilute sulfuric acid Rh and Ir are reduced by stannous chloride, the microgram quantity of arsenic is used as carrying agent. The recoveries obta- fined are in agreement with those obtained by assay method.
