摘要
本文以氢化物发生原子荧光(HG-AFS)为检测手段,通过微柱实验模式系统的考究了负载型纳米TiO2对于As(Ⅲ)的吸附行为,并与传统的反应池模式进行了对比,研究结果表明微柱实验模式能够快速的吸附溶液中的As(Ⅲ),吸附效果良好并且吸附剂可用NaOH溶液洗脱再生。损失小,操作方便快捷,可用于环境样品中As(Ⅲ)的吸附处理。
The adsorption behavior of As （Ⅲ） on silica gel - supported nanoparticle TiO2 was studied by the mierocolumn method and the batch method, respectively. The adsorbed As （Ⅲ）were determined by hydride generation atomic fluorescence spectrometry （ HG - AFS）. The results showed that the As （Ⅲ） can be adsorbed rapidly by microcolumn method, and eluted completely by NaOH solution. The present method showed the advantages of simplity, a potential application in the environmental analysis.
