提出了一种流动注射在线萃取-火焰原子吸收光谱法测定钢样中痕量钴和镍的分析方法。研究了在线萃取流程中各项最佳参数。检出限钴为0.010μg·ml~(-1)、镍为0.021μg·ml~(-1),分析速度为20～30次·h~(-1)。经钢标准样品分析验证结果可靠。
A flow injection on line extraction - flame atomic absorption spectrometry determination of trace amounts of cobalt and nickel in steel analysis method. The best parameters in the online extraction process were studied. The detection limit of cobalt was 0.010μg · ml ~ (-1), nickel was 0.021μg · ml ~ (-1) and the analysis speed was 20 ~ 30 times · h ~ (-1). The steel standard sample analysis and verification results are reliable.
