D301FC Weakly Basic Anion Exchange Resin News Report

Ion exchange resin contains a large number of hydrophilic groups, which absorb water and expand upon contact with water. When the ions in the resin change, such as the cation resin changing from h to na,anion resinThe conversion from Cl - to OH - causes expansion due to the increase in ion diameter, which increases the volume of the resin. Generally, resins with low crosslinking degree have a higher degree of expansion. When designing an ion exchange device, the expansion degree of the resin must be considered to adapt to the volume changes of the resin caused by ion conversion during production and operation.
The present invention provides a method for regenerating weakly acidic cation exchange resins and the use of organic weak acids in regenerating weakly acidic cation exchange resins. The method includes contacting a weakly acidic cation exchange resin with an organic weak acid to obtain a regenerated weakly acidic cation exchange resin. By using organic weak acids as regenerants for weakly acidic cation exchange resins, the safety of weakly acidic cation exchange resins can be greatly improved compared to strong acids such as hydrochloric acid and sulfuric acid in existing technologies. The regeneration process can be carried out at normal temperature and pressure without any other special conditions or properties
