【摘要】：以苯酚为模板,γ-脲基丙基三甲氧基硅烷为功能单体采用表面分子印迹聚合法制备了脲基功能化的苯酚表面分子印迹聚合物(苯酚-MIP),并使用红外光谱对苯酚-MIP的结构进行了表征。结果表明:在最佳条件下,初始浓度c0=150mg/L,吸附时间t=20min,pH=7,温度T=30℃下,苯酚-MIP的吸附量是非印迹聚合物(NIP)的2.32倍。动力学数据拟合结果显示:苯酚在苯酚-MIP上的吸附符合伪二级动力学模型和Langmuir等温模型。另外,选择性实验结果显示:苯酚-MIP可以快速和选择性地吸附水中的苯酚。

The structure of phenol-MIP was characterized by infrared spectroscopy. The results show that under the optimum conditions, the adsorption capacity of phenol-MIP is 2.32 times of that of non-imprinted polymer (NIP) at the initial concentration of c _ 0 鈮，
