摘　　要：研究Fe3+掺杂的TiO2薄膜对无水肼废水光催化降解作用,考察了影响Fe3+掺杂的TiO2薄膜光催化降解无水肼废水的效果的相关因素,结果表明:当Fe3+掺杂TiO2薄膜的摩尔分数为0.5%,煅烧温度为500℃,煅烧时间为3h,并且无水肼废水为中性或弱碱性,催化降解温度在30℃左右时,Fe3+掺杂的TiO2薄膜的催化效果最好。Treatment of hydrazine anhydrous wastewater by TiO2 film doped with Fe^3＋ is studied. The experimental results indicate that： when TiO2 fihn doped with 5% Fe^3＋ , the calcination temperature is 500℃, the calcination time is 3h, the wastewaler is neutral or weak alkaline, degradation temperature is about 30℃, the photocatalytic readion is most effectively.
