Sorption-atomic-absorption determination of platinum, palladium, and rhodium in dead autocatalysts

The conditions for determination and group concentration of platinum metals (PMs) in the presence of matrix components using new S,N-containing complex-forming sorbents in solutions obtained after decomposition of decontaminated autocatalysts are proposed. The technique of atomic-absorption determination of PMs from a solution (n x 10(-4)-n x 10(-2); s (r) = 0.15-0.07) and a solid phase (n x 10(-5)-n x 10(-4); s (r) = 0.20-0.12) is developed.
