摘要
以钛酸丁酯为原料,通过溶胶—凝胶法在玻璃纤维布上制备了TiO_2膜。分别以主波长253.7nm的15W紫外线杀菌灯和主波长365nm的15W兰黑管荧光灯(黑光灯)作为光源,利用所制TiO_2膜对不同起始浓度的苯酚水溶液进行了光催化氧化处理,综合分析了苯酚去除率,TOC去除率和吸光度(A)—波长(λ)扫描曲线。结果表明,杀菌灯光催化比黑光灯光催化更为有效,对苯酚具有很好的去除效果。随苯酚起始浓度的减小,苯酚去除率增大。
TiO_2 film was prepared on fiberglass cloth by sol-gel technique, using tetrabutyl titanate as starting material, and 15W 253.7nm germicidal lamp and 15W blacklight fluorescent lamp as the light sources, aqueous phenol solution with different initial concentrations were photocatalytic decomposed over TiO2 film, then analyzed the removal rate of phenol, TOC and scanning curve of absorbance (A)-wave length(λ). The result showed that photocatalysis of germicidal lamp was considerably effective than blacklight fluorescent lamp, and percentage of decomposed phenol increased with decreasing initial concentration of phenol.
