摘　　要：以苯酚、甲醛和8-羟基喹啉为聚合单体,通过反相悬浮聚合方法合成球形8-羟基喹啉酚醛树脂,以此为基础,经过高温碳化和活化,成功制备了多孔性的球形活性炭吸附剂。系统考察了作为碳化基球的酚醛树脂中N元素含量对最终球形活性炭孔结构的影响规律,在优化的合成控制条件下,制备了球形外观光滑完整、没有脱落现象且孔结构丰富的球形活性炭(8-HQC-C),并以苯酚为小分子吸附模型、VB_(12)为中分子吸附模型,考察了8-HQC-C的吸附性能,其平衡吸附量均高于商品化碳化树脂Lewatit AF50,表现出作为血液灌流吸附剂的可行性。In this paper,the spherical 8-Hydroxyquinoline phenolic resin was synthesized by inverse suspension polymerization with phenol,formaldehyde and 8-Hydroxyquinoline as polymerization monomers.On this basis,the porous spherical activated carbon adsorbent was successfully prepared through high-temperature carbonization and activation.The influence of nitrogen content in phenolic resin was systematically investigated on the formation of pore structure in the final spherical activated carbon.Under optimized synthesis conditions,spherical activated carbon 8-HQC-C was prepared with smooth appearance,no detachment phenomenon and rich pore structures.The adsorption performance of 8-HQC-C was investigated using phenol as a small molecule adsorption model and VB_(12) as a medium molecule adsorption model.Its adsorption capacity is higher than that of commercial carbonized resin Lewatit AF50,which indicates the feasibility of being used as hemoperfusion adsorbent.
