| Abstract: | 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 × 10−4−n × 10−2; s r = 0.15–0.07) and a solid phase (n × 10−5−n × 10−4; s r = 0.20–0.12) is developed. |
