【摘要】：以苯酚為模板,γ-脲基丙基三甲氧基硅烷為功能單體采用表面分子印跡聚合法制備了脲基功能化的苯酚表面分子印跡聚合物(苯酚-MIP),并使用紅外光譜對苯酚-MIP的結構進行了表征。結果表明:在最佳條件下,初始濃度c0=150mg/L,吸附時間t=20min,pH=7,溫度T=30℃下,苯酚-MIP的吸附量是非印跡聚合物(NIP)的2.32倍。動力學數(shù)據(jù)擬合結果顯示:苯酚在苯酚-MIP上的吸附符合偽二級動力學模型和Langmuir等溫模型。另外,選擇性實驗結果顯示:苯酚-MIP可以快速和選擇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，
