... solutions also containing Ca2+ and Mg2+ ions. The highest purification degree was realized for nickel (77%) and did not exceed 35% for other cations. Ni2+ ions were shown to be transported not only through the solution, but also through the ion exchanger. Ni2+ transport in zirconiu ...

It was found that the effective diffusion coefficient of Ni2+ in a macroporous strongly acidic cation-exchange resin, which was determined with the electromigration method, depends on acidity and flow rate of the solution. The values of diffusio ...

... anion-selective membrane caused a decrease in the Ni(II) amount deposited on the cationselective membrane. As a result, the nickel flux through the cation-exchange membrane increases. The apparent diffusion coefficients of Ni(II) ions in the ion exchangers containing an 8% cross-linking agent wer ...
