Hydroxide Ion Selective Permeable Membranes

Hydroxide-Selective-Membrane

Hydroxide Ion Selective Permeable Membrane

The hydroxide ion selective permeable membrane is independently developed by Tingrun. This anion membrane not only possesses the characteristics of a typical anion membrane but also has a high selectivity for hydroxide ions. It effectively retains other anions such as Cl-, SO₄²-, NO3-, with a retention rate of over 95%. Therefore, this membrane can be used to separate salt and alkali. If ion precipitation is not a concern, it can achieve 100% separation of alkali and salt.

Scope of usage

To separate the acid and salts

Working Principle:

Due to the unique property of selective permeability of hydroxide ions, the anion membrane can be stacked with the acid-resistant cation membrane to form an electrodialysis module. This module can then be used to separate alkali and salts in alkaline wastewater, while also concentrating the alkali
Principle of Alkali and Salt Separation Electrodialysis

Applications:

This can be used to separate alkali and salt in acidic wastewater through electrodialysis, while also concentrating the acid
