针对现有大孔吸附树脂选择性差、分离纯化效率较低、难以满足复杂样品分离纯化需求的难题,大孔吸附树脂功能改性成为提高其分离效率和选择性的理想途径。综述了现有聚苯乙烯型大孔吸附树脂改性的途径和制备方法,讨论修饰基团对吸附性能的影响,并就其在天然产物中的应用情况进行了综述。可为大孔吸附树脂定向设计和制备,以及深度应用研发提供参考。

In view of the poor selectivity of the existing macroporous adsorption resins and the low efficiency of separation and purification, it is difficult to meet the demand for separation and purification of complex samples. The functional modification of macroporous adsorption resins has become an ideal way to improve the separation efficiency and selectivity. The modification methods and preparation methods of the existing polystyrene macroporous adsorption resins are reviewed. The influence of the modified groups on the adsorption properties is discussed. The application of the modified groups to natural products is also reviewed. For macroporous resin orientation design and preparation, as well as the depth of application research and development provide a reference.
