纳米二氧化钛光催化降解有机磷农药的研究

Study on Photocatalytic Degradation of Organophosphorous Insecticide by Using nm-TiO_2

纳米TiO2在光催化降解水中有机污染物方面具有明显的优势,以锐钛矿型纳米TiO2(简称nm A-TiO2型)降解有机磷农药为研究对象,分别对nm A-TiO2用量,PH值、外加氧剂、光源对降解率的影响进行研究,结果表明,nm A-TiO2降解有机磷农药是有效的。

Studies have shown that nanometer titanium dioxide had obvious advantages in photocatalytie degradation of organic pollutants, nm - TiO2 was applied to phlotcatalytically degrade organophosphorous insecticide, in this paper the effects of factors such as dosage of nm - TiO2, PHvalue, exterior oxidants and light source when nm - TiO2 photocatalytically degrades organophosphorous insecticide have been studied. The results showed it was effective that organophosphorous insecticide could be photocatalytically degraded by nm- TiO2 .
