On the Ionic Conductivity of Cation Exchange Membranes in Mixed Sulfates Using the Two-Phase Model.

ABSTRACT: The concentration dependence of the conductivity of ion exchange membranes (IEMs), as well as other transport properties, has been well explained by the contemporary two-phase model (Zabolotsky et al., 1993) considering a gel phase and an inter-gel phase filled with electroneutral solution. Here, this two-phase model has been adopted and first applied in electrolytes containing mixed counter-ions to investigate the correlation between the membrane ionic conductivity and its microstructure. For three representative commercial cation exchange membranes (CEMs), the total membrane conductivity (κT) when in equilibrium with mixed MgSO₄ + Na₂SO₄ and H₂SO₄ + Na₂SO₄ electrolytes could be well predicted with the experiment
