摘要：

The extraction of noble metals with n-octylaniline at varying concentrations of different mineral acids was studied, and optimum conditions for their separation from the base metals commonly present in platinum-bearing materials were established. The successful application of the procedure to the analysis of mattes, sludges, and flotation concentrates is shown. The lower limit of determination in such materials is 100 ppm for Pt and Ir, 40 ppm for Ru, and 10 ppm for Pd and Rh. © 1979.
