摘要
提出在光催化剂TiO2 存在下添加Cu2 + 、H2 O2 作为复合催化剂 ,用紫外光 (UV)作为激发光源 ,然后辅助自然光 (S)催化降解偏二甲肼 (UDMH)废水 ,1 5 0 0mg/L的UDMH经 0 .5h的紫外光激发照射后 ,再经 7天自然光催化降解 ,降解率达 99.9%。该方法既节省了能源 ,与自然降解法相比 ,又大大缩短了废水处理周期 ,因此 ,是一种经济有效。
The method using the supported TiO 2 as catalyst, adding Cu 2+ and H 2O 2, and using ultraviolet light as arousal light source, later assisting the sunl ight photocatalytic degradation Unsymmetrical Dimethyl Hydrazine(UDMH)is an ec onomical, effective, simple and feasible UDMH waste water treatment method. It i s found that UV light up 0.5 h in 1 500 mg/L UDMH, 7 days sunlight shining on la ter, the degradation rate is 99.9%. The energy is saved and the process period i s shorten largely by this method compared with the nature degradation.
