摘要
对铜的 3条谱线 (2 49.2 nm、2 61 .4nm,3 2 4.8nm ) ,铅的 2条谱线 (2 83 .3 nm、2 1 7.0 1 nm )以及锌的 2条谱线(3 0 7.6nm、2 1 3 .9nm ) ,共 7条谱线的灵敏度、检测限、线性范围进行了归纳性总结 ,并对多种共存元素可能存在的干扰情况进行了研究 ,认为利用元素不同分析谱线的分析灵敏度差异 ,根据被测元素在样品消解液中含量 ,选择合适的谱线进行分析 ,既降低工作强度 。
The paper studied the analysis sensitivities, detect limits and lineal ranges of different spectral lines of copper(249 2nm?261 4nm?324 8nm), lead(283 3nm?217 01nm) and zinc(307 6nm?213 9nm) in flame atomic absorption spectrophotometry, and interference of coexist elements on determination In environmental monitoring the difference of analysis sensitivities of different spectral lines may be used to determinate copper, lead and zinc with different content by selected suitable spectral lines The method may not only simplify analyses steps but also obtain accurate determination results
