| Abstract: | A procedure for decomposing samples and determining rhodium in environmental objects by the catalytic method according to the reaction of sulfarsazen oxidation with periodate is proposed. The accuracy of the results is confirmed by determining rhodium using the method of inductively coupled plasma mass spectrometry. It is established that the rhodium content in the samples of road dust in Moscow is 0.01–0.04 g/t depending on the place of sampling. The standard deviation of repetition of the results of rhodium determination does not exceed 0.05. |
