  • 摘要: 以对羟基苯甲酸乙酯（EP）为印迹分子，利用溶胶-凝胶法制备出Ag/Zn-MIP-TiO2，并对其光催化性能进行了研究.从3个方面研究了Ag/Zn-MIP-TiO2的选择性：UV-Vis光谱的面积特定波长处吸光度以及浓度.3个角度的选择性因子分别为4.12、1.02与4.81，表明Ag/Zn-MIP-TiO2具有较高的选择性，且其选择性并非只是针对污染物的特征基团，而是对整个目标污染物具有特异选择性.
    Abstract: Ag/Zn-MIP-TiO2 was prepared by sol-gel method using EP as imprinted molecule, and its photocatalytic properties were studied. Moreover, the selectivity of Ag/Zn-MIP-TiO2 was investigated from three aspects:the UV-Vis spectrum, absorbance at specific wavelengths, and concentration. The selectivity factors of the three angles were 4.12, 1.02 and 4.81, indicating that Ag/Zn-MIP-TiO2 had high selectivity, and its selectivity was not only for the characteristic radical group of pollutants, but for the specific target pollutants.
