  Définition

  Permselective membrane made of ion-exchange material containing cationic groups fixed to a resin matrix which is in electroneutraly with mobile anions in the interstices of the resin.

  Note :

  When the membrane is immersed in a solution of an electrolyte, the anions in solution (counter-ions) can intrude into the resin matrix and replace the anions initially present while the cations in solution (co-ions) are prevented from entering the matrix by repulsion by the cations affixed to the resin.
