Selection of Appropriate Resins for Piezodialysis

  • F. B. Leitz

The very considerable developments of Staverman,1 Kedem and Katchalsky2 and others3 in the application of irreversible thermodynamics to ion-exchange membranes strongly suggest that it should be possible to concentrate a salt solution by passing a portion of the solution through a specially designed membrane. This phenomenon, called piezodialysis, has been observed with sodium chloride solutions.
