摘要
以20W紫外灯为光源,研究了将TiO2负载在凹凸棒石上,对染料水样进行光催化降解。由试验得出光催化反应过程中的工艺条件,在此基础上添加H2O2、Fe3+,反应1h后;染料脱色率达95%以上。
With 20 W UV light as the light source,photocatalytic degradation of dye water sample by immobilizing TiO_2 on attapulgite was studied.Technological condition of photocatalytic reaction is obtained by experiment.After adding H_2O_2,Fe~ 3+ and one hour reaction,dye decoloration rate is over 95%.
