Abstract
The effect of Na, Ca, Mg, Al and Fe on the efficiency of sorption concentration of Ru, Pd, Ir, Pt and Au chlorocomplexes on Styrosorb-514 hypercrosslinked polystyrene is studied in the presence of tributylamine ion-pair reagent. It is shown that general saline composition of the solutions strongly affects the degree of noble metal extraction. Various matrix components of rocks (Na, Ca, Mg, Al, and Fe) have a specific and different effect on the degree of sorption and extraction of the analytes. The obtained experimental data indicate that the introduction of Fe 3 + ions into a final sorption solution obtained after fusing the rock into NiS-matte and subsequent dissolution of the matte leads to an increase in the degree of Ir sorption up to 90%. Quantitative (97 ±3%) sorption of five noble metals (Ru, Pd, Ir, Pt, Au) on Stirisorb-514 is achieved by combining fusion of a solid sample into NiS-matte and introduction of Fe 3+ ions (2 g/liter) into the sorption solution. Further simultaneous determination of noble metals is possible either in the phase of sorbent using appropriate instrumental control or in the phase of the concentrate when selecting a suitable desorbtion agent.
