| 摘 要： | 针对目前光催化降解蓝藻效率较低、环境制约因素较多的现状,本研究采用表面分子印迹技术,通过液相沉积法制备了分子印迹型TiO2光催化剂(MIP-TiO2)。利用X射线衍射(XRD)、扫描电子显微镜(SEM)和紫外-可见光分光光度计(UV-Vis)等对制备的样品及其光催化降解效率进行了表征。研究结果表明:与非印迹型TiO2光催化剂(NIP-TiO2)相比,MIP-TiO2具有更高的叶绿素吸附能力,因此能够快速提高蓝藻溶液的透光性,增强光催化剂降解蓝藻的效率。

| Abstract: | In view of the current lower efficiency and more environmental constraints of photocatalytic degradation of cyanobacteria, molecularly imprinted TiO2 (MIP-TiO2) photocatalysts were prepared by liquid-phase deposition method using surface molecular imprinting technique. The prepared samples and photocatalytic degradation efficiency were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and UV-Vis spectrophotometer. Test results showed that compared with non-imprinted TiO2 photocatalyst (NIP-TiO2), MIP-TiO2 has higher chlorophyll adsorption capacity, which can famously improve the light transmittance of cyanobacteria solution and enhance the efficiency of photocatalytic degradation of cyanobacteria. |
