Abstract

The invention discloses a production method of polyphenylene sulfide-based adsorption separation resin. The production method comprises the following steps: adding a solvent to polyphenylene sulfide resin to swell the polyphenylene sulfide resin adding anhydrous tin tetrachloride and chloromethyl ether, heating and reacting above materials, and post-processing the obtained reaction product to obtain CH2Cl-containing CMPPS resin; and adding a solvent to the obtained CMPPS resin to swell the CMPPS resin, adding a catalyst and a functionalized monomer, heating and reacting above materials, and post-processing the obtained reaction product to obtain the final product polyphenylene sulfide-based adsorption separation resin. Functional groups comprising a thienyl group, a 3-aminopyridyl group and a mercapto group, introduced to the invention, have good coordination adsorption ability to heavy metal ions, and the functional groups contain N and S hetero atoms, have small relative molecular mass, and can easily coordinate with the heavy metal ions, so an excellent adsorption purpose can be reached.
