Performed are the studies on sorption concentrating of ruthenium from sulfuric solutions at variant concentrations of sulphuric acid with the use of KU-2 (КУ-2) and EDE-10P (ЭДЭ-1ОП) cation-exchange and anionexchange resins as well as a CAD (KAД) activated charcoal. It was determined that the highest possible sorption of ruthenium on all the tested sorbents from solutions containing 20 mg/l of ruthenium is observed if concentrations of sulphuric acid are within the range of 80–100 g/l. The EDE-10P sorbent have the most ability to absorb ruthenium; degree of ruthenium extraction by this sorbent doesn’t exceed 18% at L : S = 3 : 1. It has been revealed that in the case of three sorbents each contacting with the solution done in turn, the aggregate sorption degree doesn’t exceed 43%. At that, changing the order of introducing the sorbents into solution doesn’t exert a noticeable influence over the indices of ruthenium extraction into each sorbent type. It is suggested to carry out a preliminary recovery treatment of solutions in order to raise the degree of ruthenium extraction. It is shown that degree of ruthenium sorption by activated charcoal after the preliminary treatment of solutions by sodium sulfite is about four times more, that by anionite is half as much again and practically has not been changed in the case of sulfonic cation-exchange resin usage. A successive sorption by the tested sorbents from the sulfuric solutions treated with sodium sulfite guarantees almost complete extraction of ruthenium.
