纳米金属氧化物吸附金属离子的研究现状

Status Quo of Research on the Adsorption of Nanometer Metal Oxides to Metal Ions

纳米材料由于具有较大的比表面积及许多未饱和的原子,对金属离子具有很强的吸附性,纳米金属氧化物由于价格低廉、容易合成,近年来,在研究其对金属离子吸附方面受到关注。对纳米金属氧化物吸附金属离子的机理、影响因素、及应用进行了综述,提出了目前纳米金属氧化物在吸附金属离子方面存在的问题以及对其发展前景进行了展望。

Because of their huger specific surface area and many unsaturated atoms on surface, the adsorbability of nanomaterials to metal ions was very strong. Because the price of nanometer metal oxides was vile and their preparation was easy, the study on the adsorption of metal ions on nanometer metal oxides was attended in recent years. The mechanism, influencing factors and application of adsorption of metal ions on nanometer metal oxides were summarized. The problems in adsorbing metal ions for nanometer metal oxides at the present time were posed and the prospect of its development was prospected.
