Research progress of modified macroporous adsorption resin in adsorption separation

Abstract

Macroporous adsorption resin (MAR) is widely used in molecular adsorption and material separation due to its unique porous nature, surface activity and easy modification. Although there may be multiple synergistic effects in the adsorption process, its adsorption capacity is weak, and it is difficult to meet the problem of separation and purification of complex samples. The functional modification of macroporous adsorption resin is an ideal way to improve its separation efficiency and selectivity. In this paper, recent advances in the preparation of modified macroporous adsorption resins and their application in adsorption separation are reviewed, which provides a reference for further research.
