纳米二氧化钛对砷(Ⅲ)和砷(Ⅴ)吸附性能的研究

Adsorption Properties of Nanometer-size TiO_2 for As(Ⅲ) and As(Ⅴ)

研究了纳米二氧化钛对 As( )和 As( )的吸附行为。结果表明 :纳米二氧化钛在 p H1～ 1 0范围内对 As( )和 As( )的吸附率可达 99%。另外还考察了吸附时间、吸附体积、共存元素对吸附率的影响。此研究对含砷废水的处理、痕量砷的分离。

Adsorption action of nanometer size TiO 2 for As(Ⅲ) and As(Ⅴ) has been studied. In pH 1～10, the adsorption rate of nanometer size TiO 2 for As(Ⅲ) and As(Ⅴ) is both 99%. What's more, balance time, adsorption volume, saturation capacity of adsorption and interference have been studied. The research can be used to treat arsenic waste water and preconcentrate arsenic.
