光催化降解阿特拉津的研究

Study on Photocatalytic Degradation of Atrazine

以浸渍法自制复合型光催化剂铁改性金红石TiO2,以阿特拉津为目标物,在pH=3的条件下,考察铁改性金红石TiO2经可见光催化H2O2对阿特拉津的降解情况。结果表明,此反应15min,阿特拉津的降解率达到95%以上。探讨了催化剂的投量、反应体系H2O2的初始浓度、反应体系初始pH值、阿特拉津初始质量浓度、催化剂含铁量等对阿特拉津降解效果的影响。

The photocatalytic degradation of atrazine was discussed under the visible irradiation with H2O2 by rutile TiO2 modified by iron,at pH 3.It was found that the removal rate of atrzine could reach 95% above with 15 min.The addition of catalyst,initial H2O2 concentration,initial pH,initial atrazine concentration,the content of Fe in compound catalyst on the degradable efficiency of atrazine in reaction system was also discussed.
