the invention u043eu0442u043du043eu0441u0438u0442u0441u00a0 to analytical chemistry, namely, the definition of as and sb from the same samples in the presence of tin. the essence of the method u0437u0430u043au043bu044eu0447u0430u0435u0442u0441u00a0 is, first rebuilding as (v) and sb (v) and as (ill) and sb (ill) at room temperature u0433u0438u0434u0440u043eu0445u0438u043du043eu043du043eu043c and u0431u0440u043eu043cu0438u0441u0442u043e - hydrogen acid.then u044du043au0441u0442u0440u0430u0433u0438u0440u0443u044eu0442 u0431u0440u043eu043cu0438u0434u043du044bu0435 complexes u043cu044bu0448u044cu00a0u043au0430 and antimony benzene from 9 m solution H2S04 and register u043eu0441u0446u0438u043bu043bu043eu043fu043e - u043bu00a0u0440u043eu0433u0440u0430u043cu043cu044b. method u043fu043eu0437u0432u043eu043bu00a0u0435u0442 u043eu043fu0440u0435u0434u0435u043bu00a0u0442u044c as in the presence of a 400 fold excess of tin and antimony in the presence of 15 fold excess of tin 2, table 2).
