Adsorption separation is an exothermic process and macroporous adsorption resins can be regenerated by heating. It can also be treated with a regenerant.
The choice of regenerant mainly considers the following factors:
Macroporous adsorbent resins
What is the substance that needs to be resolved?
Which type of solvent can effectively dissolve impurities, generally selecting a small molecular weight alcohol, a dilute acid or a dilute alkali.
are generally resistant to salts, acids, bases, organics, but need to avoid contact with oxidizing agents.
