火焰原子吸收光谱法测定废旧二次电池中钴的含量

Determination of Cobalt in Waste Secondary Battery by Flame Atomic Absorption Spectrometer

建立了火焰原子吸收光谱(FAAS)法测定废旧二次电池中钴的方法。确定了最佳溶样方法和仪器测定的最佳条件,在选定的操作条件下,钴的检出限0.015μg/mL,相对标准偏差为0.98%～1.9%,加标回收率为98.0%～105%。用来测定废旧二次电池中的钴,操作简单、快速、灵敏度高,结果令人满意。

The flame atomic absorption spectrometer was adopted for the determination of cobalt in waste secondary battery. The best analysis conditions were selected by experiments. In given conditions, the detectionlimit of cobalt was 0.015 μg/mL, the relative standard deviation was 0.98%—1.9%, the recovery rate of the method was 98.0%-105%. This method was used to analyze waste secondary battery sampleswas simple, rapid and high sensitivity with satisfactory results.
