Notes:
Preparation of a carboxylic ion-exchange membrane by grafting poly(acrylic acid) onto cellophane is described. This membrane filters appreciable fractions of dissolved salt from solutions 1M and less in NaCl; flow rates through the membrane at 2500 psi are 0.5 cm./hr. and higher. Comparison is made of salt rejection properties and flow rates with a film of cellulose acetate in which rejection does not depend on fixed ionizable groups. Rejections of salts having ions of different charges are presented. Experimental apparatus for hyperfiltration is described.
