摘要
采用自制的纳米Al2O3,以火焰原子吸收光谱法为检测手段,考察了纳米Al2O3在静态条件下对Zn2+的吸附性能。结果表明,在pH=6时,纳米Al2O3对Zn2+有较好的吸附性能,吸附容量可达5 500μg/g。干扰离子Ni2+、Cu2+、Mn2+对纳米Al2O3吸附Zn2+影响较小,吸附于纳米Al2O3上的Zn2+可以用1 mol/L的盐酸洗脱,洗脱率达80%以上。
The adsorbaibility of the nanometer——sized Al2O3 under static condition to Zn^2＋ was detected used self - made nanometer Al2O3 by the atomic absorption spectroscope （AAS）. The result showed that the adsorbability was obtained for Zn^2＋ at pH = 6, the absorption capacity was 5500μg/g and was little affected by normal interference ions. The absorbed Zn^2＋ can be entirely eluted with 1 mol/L HCl ,the percent recovery was over 80%.
