摘要
为了开发新型功能型织物,研究了光催化竹炭纤维织物对亚甲基蓝溶液的光催化降解效果,分析了反应时间、亚甲基蓝溶液的初始浓度、pH值、光源中心与液面间距离等因素对亚甲基蓝溶液光催化降解效果的影响。结果表明,光催化竹炭纤维针织物在紫外线的照射下对亚甲基蓝溶液产生明显的降解效果,其去除率可达67.02%;亚甲基蓝溶液的初始浓度越低,降解效果越好;亚甲基蓝溶液的初始pH值越高,降解效果越好;光源中心与液面间距较小时织物的光催化降解效果较好。因此,光催化竹炭纤维针织物可用作过滤、污水处理材料等。
In order to develop new functional fabrics,the photocatalytic degradabilltys of methylene blue solution by photocatalysis bamboo charcoal fiber knitted fabric was researched.The relationships were analyzed between the removal rate and the response time,the initial concentration and pH value of methylene blue solution,the distance between the ultraviolet light centre and liquid level.The results were as follows： it indicated an obvious photocatalytic degradation effect of methylene blue solution by photocatalysis bamboo charcoal fiber knitted fabric under UV-irradiation.And the removal rate could reach 67.02%.when the initial concentration of methylene blue solution is lower,the pH value of methylene blue solution is higher,and the distance between light centre and liquid level is shorter,the effect was better.It indicated that the photocatalysis bamboo charcoal fiber knitted fabric could be used as filter materials and wastewater treatment materials.
