摘要
研究了用火焰原子吸收光谱法测定蓄电池低锑砷合金中的微量元素铜的最佳测量条件 ,包括燃助比、燃烧高度、灯电流、光谱通带以及基体元素对测定的影响。实验表明 :在选定实验条件下 ,铜的浓度在 0～ 4mg/L范围内符合比尔定律 ,相关系数 (r)为 0 9979。方法简便、快速 ,选择性好 ,结果满意。回收率在 96 %～ 97%之间 ,相对标准偏差为 1 13%。
The optimum conditions for determination of copper in Sb-As alloy in storage battery by atom absorbing spectrum of flame, including the effect of fuel ratio,flame length lamp current, spectrum and the principle elements on the determination were studied The experiment showed that under the set experimental condition, concentration from 0～4mg/L was in accordance with Beers Law, the interrelated coefficient being 0 9979 Applied to determination of copper in low Sb As alloy, this approach proved to be easy, quick and well selective, with a reclamation of 96%～97%,and relative standard deviation of 1 13%, which constituted satisfactory results
