Abstract
The electroosmotic coefficient, and the streaming potential across Nafion 120 membrane separating two uni-univalent electrolyte solutions of the same concentration have been studied. Different electrolytes have been considered, namely NaCl, LiOH, NaOH, KOH and CsOH. According to the non-equilibrium thermodynamic theories the ratio (Δφ/ΔP)/(Jv/I), with (Δφ)(electrical potential)/(gDP)(pressure difference) the streaming potential and Jv(volume flow)/I(electrical current flow) the electroosmotic quantity, approaches the unity.
