THE PERMEATION OF SALT WATER THROUGH PROTECTIVE COATINGS USING RADIOACTIVE TRACER TECHNIQUES

Abstract

Data obtained on the permeation of sodium ions, chloride ions and water molecules through eight films using radioactive tracer techniques, are presented. Permeation data on various concentrations of sodium chloride in solution show that perm-selectivity by a membrane for a particular ion may occur. Analysis of graphical presentations of data indicates that the diffusion is Fickian and on further rationalization of these data, the theoretical concepts concerning mechanisms by which ions may diffuse through a membrane are substantiated.
