摘要：
A procedure has been developed for the determining osmium using a catalytic indicator reaction of arsenic(III) oxidation with potassium bromate and neutral red in continuous flow and flow injection systems. The possibilities of the flow systems have been compared on an example of the proposed reaction, and the regularities of this reaction conducted in different flow systems have been revealed. Recommendations on the choice of the optimal variant of the flow system are given. The accuracy of the procedure has been confirmed by the results of determining osmium in a State Reference Sample.
