| 摘 要： | 采用溶胶-凝胶-浸渍法对二氧化钛进行掺铁改性,并以活性艳红K-2BP为降解模型反应物,研究了Fe-TiO2的光催化活性。结果表明:掺铁能够提高二氧化钛的光催化活性,当掺铁质量百分比为0.1%,煅烧温度为500℃,催化活性最好,当催化剂的投加量为3 g/L,通气量为600 mL/min,pH值为3时,对活性艳红K-2BP溶液紫外光照30 min的降解率可达到98.4%。 |

| Abstract: | Fe-TiO2 coupled photocatalyst was prepared by sol-gel-dipping method.Being a model reaction,the photocatalytic degradation of Reactive Brilliant Red K-2BP was investigated in Fe-TiO2 powder suspension by UV-lamp.The results showed that the addition of Fe3+ to TiO2 enhanced its photocatalytic activity,and the optimum dipped content of Fe3+ was 0.1%,the optimum value of the calcination temperature was 500 ℃;under the condition of amount of photocatalyst 3 g/L,initial pH 3,air flow 600 mL/min,the degradation rate of Reactive Brilliant Red K-2BP was 98.4% by UV-lamp irradiated 30 min. |
