Le. Romanovskaya et al., KINETIC DETERMINATION OF RARE ELEMENTS OF THE PLATINUM-GROUP IN NATURAL MATERIALS, Industrial laboratory, 60(8), 1994, pp. 443-445
Methods for kinetic determination of osmium, ruthenium: and iridium ha
ve been developed. The preparation of samples of different composition
, namely, sulfide, oxide, silicate, biogeochemical, and natural waters
, is described. Schemes are given for analysis of natural materials fo
r concentration of rare elements of the platinum group.
