Treating Methyl Orange with a Ternary Compound Photo-catalyst Fe/TiO2/ACF Combined with Pulse Discharge

  • 摘要: 采用溶胶-凝胶法制备了Fe/TiO2/ACF三元复合光催化材料,将其投入到脉冲放电水处理反应器中降解甲基橙,考察该材料的光催化性能,以及它与脉冲放电的联合降解过程中操作因素的影响. 结果表明,Fe/TiO2/ACF三元复合光催化材料与脉冲放电产生协同作用,大大提高了对甲基橙的去除率. 甲基橙的去除率与掺铁量〔以摩尔分数计〕、煅烧温度、溶液电导率和pH有关. 当掺铁量为0.07%,煅烧温度为900 ℃时,降解效果最佳;当溶液pH为6,电导率为300 μS/cm时,对Fe/TiO2/ACF与脉冲放电的联合降解效果有利.
