Description

Elec-Trodialysis with Bipolar Membrane is mainly used to prepare acids and bases. It can convert the salts in the aqueous solution to the corresponding acids and bases without introducing new components. 

The Working Principle

The bipolar membrane is a new type of ion exchange composite membrane, which is usually composed of a cation exchange layer and an anion exchange layer. It can be made into different membrane materials with different charge density, thickness and performance under different composite conditions. Performance and use of bipolar membranes. The most basic principle of these uses is the dissociation of water molecules in the bipolar membrane interface layer under reverse pressure (also known as bipolar membrane hydrolysis), that is, the decomposition of water into hydrogen ions and hydrogen oxygen Root ion. Bipolar membrane electrodialysis is developed on the basis of the above-mentioned hydrolysis and ordinary electrodialysis principles. It uses bipolar membranes to replace part of the anion and cation membranes of ordinary electrodialysis or in ordinary electrodialysis. It is composed of a bipolar membrane in between. The most basic application of bipolar membrane electrodialysis is to prepare corresponding acid (HX) and alkali (MOH) from salt solution (MX).Under the action of the field, the salt anion (X-) enters the acid chamber through the anion exchange membrane, and generates acid (HX) from the hydrogen ion dissociated from the bipolar membrane; while the salt cation (M+) enters the alkali chamber through the cation exchange membrane, where The hydroxide ions dissociated with the bipolar membrane form alkali (MOH).

Applications

  1. Organic salt production organic acid base/inorganic salt production inorganic acid base
  2. Ferrate preparation
  3. Chemical synthesis in organic phase
  4. Uranium processing wastewater treatment
  5. Regeneration of sodium sulfate in the production of rayon
