Abstract

Aqueous solution of 1, 4-dioxane of different concentration was transported across freshly impregnated anisotropic cellulose acetate membrane at 298K, under the influence of pressure difference and electrical potential difference. The transport properties studied were hydrodynamic flow (JV )Δᶲ = o and electro-osmotic flow ( JV ) ΔP =o. The data revealed that both hydrodynamic flow (JV )Δᶲ = o and electro-osmotic flow ( JV ) ΔP =o decreases with increase in concentration but increases with increase in potential difference and electrical potential difference across the membrane. The phenomenological coefficients L11 and L12 were also studied.
