负载型TiO_2∶Fe^(3+)处理有机污染水

Photocatalytic Degradation of Organic Compound in Water by TiO_2∶Fe^(3+) coated on glass filbres

用溶胶—凝胶法制备了玻璃纤维负载的TiO2 ∶Fe3 + 光催化剂。研究了Fe3 + 掺入量、反应液起始 pH值及O2量、光源条件等对有机物去除率的影响。结果表明 :最佳掺入量为 1.5 % ,起始 pH值范围 6～ 8,空气流速为 0 2m3 ·h-1时光解率较高 ;太阳光与 3 0W紫外灯照射光解率接近 ,在太阳照射下光催化反应 4h ,CODcr去除率达 95 %

The photocatalysis of TiO 2∶Fe 3+ coated on glass filbres was prepared through the sol-gel method.The influnce of the amount of Fe 3+ doped,the original pH of solution,concentration of oxygen,kinds of lamp was investigated.
