| 摘 要： | 研究了在可见光条件下,用实验室合成的Fe3＋掺杂TiO2为催化剂催化降解酸性红染料,重点考察了Fe3＋的掺杂量、Fe3＋掺杂TiO2为催化剂的添加量、酸性红溶液的初始浓度、溶液pH值、光照时间对降解率的影响.实验结果表明,Fe3＋掺杂比为1.5%、催化剂用量为1.5 g/L、pH为2.0、质量浓度为40 mg/L的酸性红100 mL,用白炽灯光照降解酸性红30 min,酸性红降解率可达98.45%.

| Abstract: | Selecting acid red dye as the target of degradation,visible light catalytic reaction was studied with Fe3+ doped TiO2 catalyst.The influences of the amout of doped,catalyst amount,initial concentration,pH value and illumination time were examined.The experimental results showed when the Fe3+ doped ratio was 1.5%,catalyst dosage was 1.5 g/L,the pH vaiue was 2,the concentration of acid red was 40 mg/L,the solution volume was 100 mg/L,irradiation time was 30 min,the degradation rate of acid red could come up t... |
