Non Equilibrium Thermodynamic Studies on Membrane Phenomena "Streaming Potential and Streaming Current"

Streaming potentials and streaming currents developed during the streaming of water and aqueous solutions of NaCl, KCl and MgCl2 in the concentration range 10-4 to 10-4 mol/l through progesterone plug membrane have been measured and their dependence on applied pressure differences has been investigated. The results have been explained on the basis of the theory of non-equilibrium thermodynamics. It has been observed that streaming potentials and streaming currents both depend linearly on applied pressure differences and Saxen?s relationship holds good.
