Fe3+/TiO2薄膜光催化降解UDMH废水的研究
Treatment of Unsymmetrical Dimethyl-hydrazine Wastewater by TiO2 Film Doped with Fe3+
【摘要】 研究Fe3+掺杂的TiO2薄膜对偏二甲肼废水光催化降解作用,考察了影响Fe3+掺杂的TiO2薄膜光催化降解偏二甲肼废水的效果的相关因素,结果表明最佳操作条件为: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,催化降解反应时偏二甲肼废水为中性或弱碱性,催化降解温度为25℃。
【Abstract】 Treatment of unsymmetrical dimethyl-hydrazine(UDMH)wastewater by TiO2 film doped with Fe3+ was studied.Results indicated that the film was the most effectively under the conditions of TiO2 film doped with 5% Fe3+,calcinations temperature 500℃ and calcinations time 3h,with wastewater of neutral or weak alkaline,degradation temperature 25℃.
