碩士 === 中央警察大學 === 水上警察研究所 === 102 === Pollution in the ocean occurs often. Once the oil releases, there might be a series of its diffusion, drifting, evaporation, dissolving, precipitation, oxidation and emulsification. It would be a disaster without being carefully handled. Contemporarily, the most often used way in coping with oil pollution is bioremediation. However, the slow process is the defect. In order to speed up the degradation process, this paper which aims at light oil as experimental focus will argue that TiO2 nanometer photocatalyst can provide a framework for pollution substance decomposition. In the research, gasoline, octane and benzene is added with 100μl of TiO2 nanometer photocatalyst and irradiated by UV lamp for 4 hours. And the outcome analyzed by two-stage pyrolysis-GC/MS shows to a fine and rapid effect. The decomposition rate in 100μl of octane is 86%, and that in 10μl of benzene, 50μl of benzene, 10μl of gasoline and 50μl of gasoline almost reaches up to 100%. Methods and process of the experiment will be described below. Contemporary apparatus and measures for dealing with oil pollution will also be provided. Most of the oil pollution in the ocean can be solved by human labor. However, there might always be some spots and corners which cannot be cleaned totally. Given that the ability of ocean self-cleaning is limited, TiO2 nanometer photocatalyst is a new idea in ocean pollution prevention and cure.
