三硝基甲苯分子印迹微球的制备与应用
Preparation and application of TNT molecularly imprinted microspheres
摘要
Abstract
The molecularly imprinted polymers(MIP)were prepared by precipitation polymerization method using 2,4,6-trinitrotoluene(TNT)as the template molecule and acrylamide(AM)as the functional monomer.The interaction between TNT and AM was studied by UV spectroscopy.It was found that TNT and AM had a strong force,which could help to form MIP with stable structure and binding ability.The morphologies of the polymers were observed by scanning electron microscopy (SEM).It was found that the polymers prepared with 100mL acetonitrile under slow stirring were better than others.The equilibrium adsorption experiments showed that there were two kinds of adsorption sites and the adsorption capacity increased with the increase of initial concentration of TNT.Kinetic adsorption experiments showed that the adsorption rate of MIP was much quicker than that of non-imprinted polymers(NIP).Meanwhile,the specific adsorption of MIP was also tested.The results showed that MIP had strong specific adsorption properties to TNT,while the adsorption to the structural analogues of TNT(DNT and RDX)was quite weak.关键词
