摘要：以悬浆态TiO2为光催化剂,在紫外光催化反应器中,进行了苯酚溶液的动态光催化降解性能的研究,考察了TiO2用量、TiO2焙烧温度、溶液pH值以及循环流量对苯酚光催化降解的影响。结果表明,TiO2用量1.0 g/L,TiO2焙烧温度450℃,循环流量20 L/h,紫外光照反应5 h,苯酚去除率为71.2%。
Photocatalytic degradation of phenol in water by TiO2 suspension was carried out in UV - photoreactor. Effects of some important factors, such as the quantity of titanium dioxide, pH value, circulating flow, on the process of photocatalytic degradation were investigated. The experimental results showed that degradation rate of phenol could reach 71.2% when the quantity of TiO2 was 1.0 g/L, the calcinations temperature of TiO2 was 450 ℃, the circulating flow was 20 L/h and the time of UV radiation was 5 h.
