摘　　要：采用沉淀聚合法制备了苯胺分子印迹聚合物微球(MIP)和空白分子印迹聚合物微球(NIP),并对其吸附动力学、吸附热力学、选择性吸附性能和再生吸附性能进行了对比,同时进行了Scatchard分析。结果表明,MIP对苯胺具有特异选择性吸附能力,吸附行为属于单吸附层的化学吸附,可多次循环使用,且MIP比NIP具有更高的吸附效率,可用于环境污水中苯胺的选择性吸附。We prepared aniline molecularly imprinted polymer microspheres(MIP)and blank molecularly imprinted polymer microspheres(NIP)by a precipitation polymerization method,compared the adsorption kinetics,adsorption thermodynamics,selective adsorption performance,and regeneration adsorption performance,and performed Scatchard analysis.The results show that MIP has specific selectivity adsorption performance for aniline,and the adsorption process belongs to the monomolecular layer chemical adsorption,which can be recycled for many times.MIP has higher adsorption efficiency than NIP,indicating that it can be used for selective adsorption of aniline in environmental sewage.
