The barrier is subsequently contacted with a second aqueous solution and a direct electric current is passed through said barrier and second solution in a direction substantially parallel to the smallest dimension of the barrier thereby facilitating desorption of at least one of the sorbed components from the barrier into the second solution which solution is thereafter removed. |
