Abstract
Impact from Counterion Nature on Current Transfer Through Structural Fragments of Sulphocationic Resin
Highlights
One of the most prospective ways of wastewaters and mine waters demineralization is electrodialysis
The impact of ionic form on moisture content in resin in 0.1 M electrolyte solutions is shown in Figure 2 as W dependence from the counterion radius
As shown in the figure, the moisture content of the KU-2 resin depends on the nature of the counterion and naturally decreases with resin transition from H+ to NH4+-forms
Summary
One of the most prospective ways of wastewaters and mine waters demineralization is electrodialysis. Among many studies, little attention is being paid to the practical application of electrodialysis impact of counterion nature on the current transfer through structural fragments of ionite. In order to simulate the processes of electrical mass transfer in such electrodialyzers with filler, it is necessary to have the information on transportation and structural parameters as well as the mechanism of the current transfer in the ion-exchange membrane (Berezina et al 2008, Karpenko-Jereb et al 2009, Demina et al 2016b), and in resin. There is plenty published data on the electrical conductivity of ion-exchange resin in electrolyte solutions of different nature, but the information on the mechanisms of the current transfer in these materials is not available
