    摘要: A novel, heterogeneous ion exchange membrane, methods for making such a membrane, and devices containing such a membrane are disclosed. Such membranes comprise linear low or linear medium density polyethylene or high molecular weight high density polyethylene as a binder and can incorporate a wide variety of ion exchange resin materials. The membranes can be fabricated using extrusion or other melt processing procedures to produce a product, which upon conditioning in water, exhibits properties adapted for use in numerous applications.

    摘要: An improved ion retardation method for separating mixtures of salts in aqueous solution is disclosed. In this method, an ion retardation resin containing excess strong base groups is employed wherein the strong base groups have associated therewith a counteranion for which the strong base group has less affinity than for the anion of the salt which is last eluted from the resin.
