对-特辛基酚表面印迹聚合物的制备及吸附性能评价

Preparation and evaluation of adsorption properties of p-tert-octylphenol surface molecular imprinted polymers

以对-特辛基酚为模板、甲基丙烯酸为功能单体制备了对-特辛基酚表面印迹聚合物.采用扫描电子显微镜、紫外光谱以及红外光谱对印迹聚合物进行表征,通过平衡吸附实验对聚合物的吸附性能进行评价.结果表明:该分子印迹聚合物对对-特辛基酚具有较大的吸附容量和良好的选择性,其最大吸附量Qmax约为86.12mg/g.

Surface molecularly imprinted polymer was synthesized by using PTOP as template moleculer and methacrylate as function monomer.The imprinted polymer was characterized by scanning electron microscope（SEM）,fourier transform infrared spectroscopy（FTIR） and ultraviolet（UV）.The binding capacity was evaluated by balance adsorption.The result showed that the imprinted polymer has high adsorption amount and good selectivity toward PTOP and maximum adsorbing capacity was about 86.12 mg/g.
