Non-equilibrium thermodynamic studies on transport of aqueous aluminium nitrate solutions across cellulose acetate membrane

Abstract
Hydrodynamic and electro-osmotic permeability
measurements of water and aqueous solutions of Al (NO3)3.9H2O
in the concentration range of 10-4 M to 10-3 M have been
made across cellulose acetate membrane.
The data obtained have been used to determine the transport equation using the
theory of non-equilibrium thermodynamics. Streaming current generated during
the transport of various permeants was also measured and its dependence on
pressure investigated. Phenomenological coefficients have been determined using
the transport equation and Saxen’s relationship verified. Zeta potentials have
been evaluated using electro-osmotic permeability and membrane-permeant
conductance data. It has been observed that hydrodynamic and electro-osmotic
permeabilities depend linearly on applied pressure difference and potential
difference respectively.
