method of atomic absorption analysis of precious and nonferrous metals in mineral raw materials of varied composition

摘要

the invention reduces the production time and allows for the analysis of precious and nonferrous metals in the presence of an applied by acid decomposition u0430u043cu043cu043eu043du0438u0439u043du043eu0439 salt acid and other acids.the acid decomposition of an analyzed sample sample contained one process the solution mixture of acids and other acids from u0440u0430u0441u0447 u0430u043cu043cu043eu043du0438u0439u043du043eu0439 salt this 10 ml acid 1.5 - 2 g u0430u043cu043cu043eu043du0438u0439u043du043eu0439 other acid salt.
