| Summary: | 碩士 === 逢甲大學 === 環境工程與科學學系 === 107 === Neonicotinoid is one of the most widely used insecticides in the world. It protects crops with insecticides, but it also affects the life of bees and leads to crop harvesting. It is mainly represented by midacloprid, Thiamethoxam, Acetamiprid and Clothianidin. Experiments were carried out with these four insecticides.
Therefore, this study is divided into two parts. The first part is to prepare metal TiO2, doped with Ferric nitrate, Silver nitrate and simultaneously doped with iron and silver to degrade neonicotinoid insecticides. Photocatalyst analysis is performed by reflection spectroscopy, X-ray diffraction analysis, etc., and the second part is used for film preparation by using a recovery material of cellulose triacetate to separate photocatalysts after photodegradation, and to use a particle size analyzer and nano particles. Tracking the performance of the analyzer after separation, the photocatalyst analysis, photodegradation effect and separation effect are used to obtain the optimal conditions for photocatalytic degradation and separation.
