Technical Field

Background
Electrolysis is a process of synthesizing a high-purity substance from chemicals and treating the surface of a material by utilizing an electrochemical reaction occurring at the interface between an electrode as an electron conductor and an electrolyte as an ion conductor. When the power is on, cations in the electrolyte move to the cathode to absorb electrons, and a reduction reaction is carried out to generate a new substance; the anions in the electrolyte move to the anode to release electrons, and an oxidation reaction occurs to generate a new substance.
Ion exchange is the action or phenomenon of exchanging ions in solution with ions on certain ion exchanger, and is the aim of extracting or removing some ions in solution by means of exchanging ions in solid ion exchanger with ions in dilute solution, and is a unit operation belonging to mass transfer separation process. The ion exchange membrane is a thin film made of a polymer material (there are also inorganic ion exchange membranes, but their use is not yet common) having ion exchange properties. Since its ion permselectivity is generally mainly utilized in application, it is also referred to as an ion permselective membrane.
