二氧化钛光催化降解酸性嫩黄的研究

Photocatalytic Degradation of Acid Light Yellow Wastewater Using TiO_2

研究了二氧化钛在紫外光下,对酸性嫩黄模拟染料废水的光催化脱色效果。研究结果表明,当酸性嫩黄溶液初始浓度为100 mg/L,溶液初始pH为4,二氧化钛的投加量为0.34%,光催化反应80分钟,其脱色率可达93%。二氧化钛的煅烧温度为450℃时,催化效果最好。光催化氧化法是处理酸性嫩黄染料废水的有效方法。

Photocatalytic degradation of acid light yellow solution with TiO2 in UV light was investigated. The results show that the initial concentration of Acid light yellow is 100 mg/L and the initial pH of solution is 4 with 0.34 % of TiO2, and reacted for 80min in UV, the decoloration rate is 93 %, The results showed that the catalytic efficiency of TiO2 calcined at 450 ℃ was more effective. Photocatalytic degradation is an effective method for treatment of acid light yellow wastewater.
