摘要
通过对负载了丁二肟的活性炭对镍的吸附和富集行为的研究,确立了活性炭负载丁二肟和其对镍的吸附洗脱条件。建立了负载丁二肟活性炭对镍富集、分离,再用原子吸收测定的分析方法。方法的富集倍率为40倍。对地表水的测定结果令人满意。
Adsorption and enrichment of nickel on activated carbon pregnated with demethylglyoxime were studied. The optimal conditions of dimethylglyoxime carried on activated carbon and its adsorption and elution to nickel were selected. A new separation and enrichment method for the determination of nickel by atomic absorption spectrometry has been developed. The enrichment factor is 40 for nickel. The proposed method has been used to determinate nickel in the ground water with satisfactory results.
