太阳能分解水中有机磷农药

太阳能分解水中有机磷农药 STUDY ON THE DECOMPOSITION OF ORGANO-PHOSPHOROUS INSECTICIDE IN WATER BY USING SOLAR ENERGY 高翠琴 1 first-author 董玉林 1 董庆华 1 武汉大学化学系 武汉大学化学系 研究了照射光源、催化剂种类对水中有机磷农药（马拉硫磷）分解速度的影响。结果表明,远紫外光能够光分解马拉硫磷,若用波长大于360nm的光作为动力,在有TiO 2 和氧存在的条件下,马拉硫磷可以发生光催化分解反应;在适当条件之下,太阳光也可以分解水中的马拉硫磷。 The influences of light source, photocatalyst and other factors on the photo-decomposition of organo-phosphorous insecticide （malathion） in water have been investigated. It was found that the malathion was photolysis by ultraviolet light, and could be decomposed rapidly by means of semiconductor photocatalytic reaction the presence of oxygen. By using of solar energy the photocatalytic decomposition of malathion in water is possible. 半导体光催化反应 二氧化钛 马拉硫磷 太阳能 semiconductor photocalytic reaction titanium dioxide malathion solar energy O644.14 国家自然科学基金资助课题 1992-03-01 2021-04-01 3
