摘要
以紫外灯为光源,在WO3粉末悬浆体系内,对亚甲基蓝溶液光催化反应进行研究,讨论了催化剂用量、有机物浓度、外加H2O2量、pH值、光照时间等因素对光催化结果的影响,研究了提高光催化效率的方法。
Photo- catalytic reaction of methylene- blue in WO3 powder suspension irradiated by ultraviolet lamp is studied. The influencing factors such as dosage of catalyst, concentration of the organic pollu tants, dosage of H2O2 ,pH value and illumination time are studied in details. Methods to raise photo - catalytic efficiency are studied.
