| 摘 要： | 采用溶胶-凝胶法制备TiO2粉末,通过溶液共混法制备PVA/SA/TiO2复合膜,并研究了其对甲基橙的脱出效果。实验证明,由经500℃绝氧煅烧TiO2掺杂制备而成的复合膜对甲基橙具有良好的降解效果;降解效果随着复合膜用量的增加而增加,随光照时间增加而有所提高,随着甲基橙初始浓度的增加而下降。

| Abstract: | Titanium dioxide powder was prepared by the sol - gel method, blend membranes filled with TiO2 were prepared for the degradation of methyl and the orange. polyvinyl alcohol/sodium alginate The effect of illumination time, composite membrane dosage, and the initial concentration of methyl orange on the degradation rate of methyl orange were investigated. As a result, the composite membranes performed excellently for the degradation of methyl orange. |
