| 摘要：以钛酸四丁酯为原料，采用溶胶一凝胶法制备了TiO 和不同含铁量的铁氮共掺TiO ，并用
荧光光谱对其进行表征；研究了紫外光照射下对孔雀石绿的降解，对比考察了不同掺杂的TiO 、不
同比例掺铁量的共掺杂TiO ，以及催化剂的用量和不同浓度下的降解；结果表明：当Fe／Ti的质量
分数为0．9％，用量在2 L时，孔雀石绿的降解效果最好，孔雀石绿的最佳降解质量浓度为
5O mg／L，150 min的降解率可达98．96％；而且荧光表征显示：样品的荧光强度越小，催化效果越好。 |

| Abstract：Nano—particles，diferent iron content in the iron and nitrogen codoped TiO2 were prepared by sol—gel
method with C16H36O4Ti as raw materials，and fluorescence spectrum was used to study the structural characterization．
The catalyses in the ultraviolet irradiation effects on the degradation of malachite green was studied，the influence
of different impure TiO2，diferent iron codoped TiO2，dosage of the activators and concentration of malachite
green were compared．The results indicated that when the Fe／T molar ration of 0．9％ and the dosage is 2 g／L．the
photo catalytic degradation of malachite green is the best．The best concentration for degradation of malachite green
is 50 mg／L，the rate in 150 min can reach 98．96％ ．And the fluorescence spectrum showed that the less fluorescence
intensity，the better catalytic efect of the specimen． |
