ABSTRACT:
An ion selective semipermeable membrane such as is used in electrodialysis cell assemblies is fabricated with an unreacted border region of a polymer film which is heat sealable to itself and to other materials of similar composition. Within the border region are sealed two flow port connections to pass ionic process liquid across the face of the membrane. The border regions of one membrane are heat seal bonded at the edge to the border regions of a subsequent membrane in a sequence to form an electrodialysis cell assembly accordion bellows like in configuration. The flow ports communicate with the compartments so formed. Membranes produced by chlorosulfonation of polyethylene are especially suitable for heat sealing.
