Sorption preconcentration of noble metals (NMs) chlorocomplexes on new polyvinylpyridine sorbents were investigated. The new pyridinium-containing sorbents occur high sorption capacity in dynamic and static modes of preconcentration. It was established sorption degree of Ru, Rh and Ir largely depend on form of these ones in solution. It is supposed that pyridinium-containing sorbents function as a complexing ion exchanger.
