Ion exchange membranes for use in dialysis

Reichelt Chemietechnik is an experienced laboratory supplier and a specialized provider of laboratory equipment and various components for industrial filtration technology. Within our product range, we offer numerous membranes, including ion exchange membranes for laboratory and production applications. Specifically, we supply ion, anion, and cation exchange membranes for various dialysis processes. Special electro-dialysis membranes for laboratory and production applications are also available, all of which are of high quality and offered at reasonable prices.

In which areas are ion exchange membranes needed?

Ion exchange membranes are excellent for separation processes because they selectively allow only certain ions to pass through: cation exchange membranes are suitable for cations, and anion exchange membranes only for anions. In recent years, the use of these types of membranes for separating substance mixtures has gained increasing importance, as these separation technologies are highly efficient and make sense on a large scale and from an economic perspective.

The membrane types offered by Reichelt Chemietechnik are made of PS (polystyrene) and HDPE (high-density polyethylene). The high mechanical tensile strength and tear resistance of the materials used are crucial in this context.

Application in electrodialysis

Ion exchange membranes for electrodialysis are known for their high resistance to organic and inorganic media. They are well-suited for the recovery of acids from pickling solutions for copper refining and for galvanic baths. But they are also used for desalting seawater or brackish water, as well as for processing sugar solutions, whey, and other aqueous and non-aqueous solutions containing ions. In addition, we offer membrane types for acid dialysis or base dialysis.

How do these membranes work, anyway?

Ion exchange membranes separate the space between two electrodes, with the electrode space being separated by alternating anion and cation exchange membranes. This is referred to as an ion exchange pair. Each pair forms a separate functional unit, a so-called cell. When an electrical direct current is applied to the electrodes, the anions migrate to the anode. The anions can easily pass through the positively charged anion exchange membrane but are stopped by the nearest negatively charged cation exchange membrane. The same happens with the cations, resulting in the effect and outcome of electrodialysis with the enrichment of salts in the cell or cells in large-scale processes.
