Eg. Khomutova et al., KINETIC DETERMINATION OF PLATINUM METALS IN PYRRHOTINES AND PRODUCTS PROCESSED FROM THEM, Industrial laboratory, 61(12), 1995, pp. 705-707
A method for analysis of pyrrhotine concentrates and products processe
d from them that has a kinetic final stage is presented. The relative
standard deviation does not exceed 0.20 (Rh), 0.19 (Ru), and 0.17 (Ir)
in the concentration range of 0.05 - 10 g/ton for Rh and 0.01 - 1.0 g
/ton for Ru and Ir.
