摘要

the invention u043eu0442u043du043eu0441u0438u0442u0441u00a0 to analytical chemistry and can be used in the chemical and metallurgical industry in the analysis of residuals obtained with the u0432u044bu043fu043bu0430u0432 ke of non-ferrous metals. the purpose of u0438u0437u043eu0431u0440u0435u0442u0435u043du0438u00a0 simplification of analysis and reducing the time it u043fu0440u043eu0432u0435u0434u0435u043du0438u00a0. method includes the decomposition of samples in a mixture of acids, and the subsequent determination of elements of atomic u044du043cu0438u0441u0441u0438u043eu043du043du044bu043c method with u0438u043du0434u0443u043au0442u0438u0432u043du043e u0441u0432u00a0u0437u0430u043du043du043eu0439 plasma.u0434u043bu00a0 u0440u0430u0437u043bu043eu0436u0435u043du0438u00a0 samples using a mixture of phosphoric and nitric acids, u0432u0437u00a0u0442u044bu0445 mass relative to the sample (136 170), (101, 151): 1, with 250 - 300 & deg;. 2, table 2).
