Electrical conductivity of flexible strongly acidic resin loaded with Cr (III) was investigated with an impedance spectroscopy method. The purpose of the work was to estimate the influence of hydrostatic pressure drop on the conductivity of the ion-exchanger bed, which had been compacted previously.

Ni2+ transport in zirconium hydrophosphate containing 85% water was investigated with the electromigration method. An effective diffusion coefficient of Ni2+ was found to reach 1.14×10!11 m2 s!1. It was shown that zirconium hydrophosphate can be used for discontinuous Ni2+ removal from diluted solut

The organic ion exchangers (Dowex HCR-S, Dowex 50WX-2) and inorganic ion exchangers with phosphate functional groups (zirconium phosphates ZrP-1, ZrP-2) were studied as transport media for ion-exchange-assisted electrodialysis of diluted solutions containing Cu (II) ions. The ion-exchange and electr

The removal of nickel ions from diluted solution using some ion-exchange resins (Dowex MSC-1, Purolite C 100E, KU 2-8 and Dowex HCR-S) was studied. The purification process involved the use of an electrodialysis-type cell in which the centre compartment was filled with a packed bed of ion-exchanger
