Anion exchange resin refers to an ion exchange resin containing alkaline groups in molecules. It is alkaline in solution and can exchange anions in solutions with its hydroxyl ions. It can be divided into three categories: strong alkaline, weak alkaline and strong and weak alkaline mixture.
The ion exchange process is a kind of ion exchange process between ions in the liquid phase and ions in the solid phase Anion exchange resin Anion exchange resin Reversible chemical reaction, when some of the ions in the liquid phase are more ion exchange solids prefer, they will be adsorbed by the ion exchange solids, in order to maintain the electrical neutrality of the aqueous solution, so the ion exchange solids must be released equivalent ions back into the solution.
It is used for the treatment of water (including hard water softening, high-pressure boiler water, non-ionized water, injection water, seawater desalination, etc.) of harmful anions (such as cyanide ions, thiocyanate ions, etc.) in wastewater, the extraction of rare elements, and the separation of amino acids, tartaric acid, citric acid, etc.
