| Abstract: | 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. |
