TiO_2-Cu~(2 )体系降解偏二甲肼的研究

研究了在TiO2 催化氧化降解偏二甲肼的反应体系中添加Cu2 的效果以及Cu2 浓度、添加H2 O2 、反应体系A/V值以及紫外光与太阳光作光源对偏二甲肼降解率的影响 ,结果表明 ,在TiO2 光催化降解偏二甲肼的反应体系中Cu2 的最佳投加量为 4 0mg/L ,添加适量H2 O2 以及在紫外光照射下 ,适当增大反应液的A/V值都会大大提高偏二甲肼的降解率。同时也研究了偏二甲肼降解中间产物随着反应进程的降解规律。

Phtocatalytic Degradation of Unsymmetrical Dimethyl Hydrazine(UDMH) by UsingTiO_2 Cu~(2 ) as catalyst

The paper studies photocatalytic degradation of UDMH in TiO 2 Cu 2 suspension with sunlight or UV-light The effect of adding Cu 2 and H 2O 2,the condition of Cu 2 and the condition of reactor active area(the value of A/V) are also investigated.The results indicates that the best performance can be gained by using Cu 2 40mg/L,providing UV-light,adding proper H 2O 2 and increasing the A/V of the reactor area.The main degradate products of UDMH can also be oxidized into inorganic molecule
