Investigation of sorption of palladium, ruthenium and rhodium ions from nitric acid solutions sorbents of different sorts

Data are obtained on the Pd, Ru and Rh platinum metal ion sorption from nitric acid solutions on ion-exchange resins and nonorganic sorbents of different classes. It is determined that the sorbent capacity in relation to palladium is 1-2 orders higher of corresponding capacities in relation to ruthenium and rhodium. Series of sorption ability of sorbents are determined in relation to ions of considered elements in 3 mol/l HNO3
