A method for the electro-decontamination of spent ion exchange resin contaminated with hematite under dynamic conditions using sulfuric acid solutions has been suggested. It has been shown that decontamination under dynamic conditions excludes the secondary adsorption of radionuclides on ion-exchanger sites. The efficiency of this approach has been compared to that of control experiments without direct current treatment. A positive effect of the introduction of Fe2+ on the rate of dissolution of hematite has been demonstrated. This allows for decreasing the concentration of the sulfuric acid solution without decreasing the decontamination efficiency.

Статья посвящена одному из современных методов и технологий извлечения никеля, кобальта и меди из многокомпонентных растворов - сорбционный метод. В качестве сорбентов выступают ионообменная смола КУ-2-8 и хелатообразующие смолы. Рассмотрен один изметодов удаления веществ, сопутствующих, мешающих извлечению ценных компонентов, одним из которых является железо. The paper considers one of the modern methods and technologies of nickel, cobalt and copper recovery from multicomponent solutions; that is a sorption method. KU-2-8 ion exchange resin and chelating resins are present as sorbents. One of the method of substances which prevent removing valuable components is discussed. One of such substance is considered to be iron.

Abstract The metals Mn, Mg, Co, Cu, and Zn were separated by using an anion exchange resin column and progressively less concentrated IIC1 solution as eluting agent. The position of Mg on an anion exchange resin, not previously reported in the literature, was determined. It has been shown that by using two different ion exchange resin columns, simple hydrochloric acid solutions as eluants, and polarographic or flame photometric determinations, 12 metals can be separately estimated in an aqueous solution containing about 100 /μg of each. It is recommended that the study of ion exchange resin separation of metals found in plants be continued.

The exchange behaviour of some divalent transition metal ions M2+ (Zn2+, Cu2+, Ni2+, Co2+, Mn2+) in a zeolite NaX (SiO2/Al2O3 2.75) was studied at intermediate stages before equilibrium. The equivalent counter ion supply in the solution, given by the equivalent ratio of the two counter ions 2M2+/Na+, was found to be critical in determining the saturation level of exchange. The series of relative abilities of exchange was very similar to the well known selectivity series at equilibrium. It is suggested that water exchange of the metal ions in solution could be one of the factors controlling the relative ease of ion exchange.
