摘要
采用溶胶-凝胶法制备S-N共掺杂改性纳米TiO2溶胶,通过浸渍工艺对棉织物进行整理,制备出织物负载S-N共掺杂TiO2薄膜。探讨了在日光灯照射下,其对活性红MS模拟活性染料废水的光催化活性。结果表明,在日光灯照射下,织物负载S-N共掺杂TiO2薄膜的光催化降解率大大高于织物负载TiO2薄膜的降解率;对活性红MS的光催化降解效果随染液中氯化钠浓度的升高而降低,随碳酸钠浓度的升高而提高。
By sol-gel method, S-N co-doping nano-TiO2 sol was prepared, and S-N co-doping TiO2 thin film carried fabric has been prepared by using dipping process. The photocatalytic activity of S-N co-doping TiO2thin film carried fabric was studied by the degradation of reactive red MS simulated as reactive dye wastewater under the VIS irradiation. The results showed that the photocatalytic degradation of reactive red MS was good by using SN TiO2 thin film carried fabric under the VIS irradiation. In addition, the degradation rate of reactive red MS was decreased with the increace of concentration of sodium chloride, the degradation rate increased as the concentration of sodium carbonate increased.
