Abstract

Electrokinetic studies of different permeants across interfaces of urinary bladder membrane, testosterone membrane, liquid membrane generated by cholesterol and some inorganic membranes have been reviewed. Electrokinetic energy conversion maxima and degree of coupling have been analysed for different systems. It has been found that energy conversion maxima and degree of coupling differ significantly even for the same permeant using different membranes. The interaction of the membrane with permeating material seems to be a decisive factor in such situations. Generally it has been observed that degree of coupling and energy conversion maxima decrease with increase in concentration except for urinary bladder membranes which responds to some of the living characteristics. The behaviour of the membrane-permeant system has been explained in terms of electrokinetic (zeta) potential and various other factors related with interfaces.
