摘　　要：火焰原子吸收分光光度法是用于分析检测金属元素浓度的重要化验方法之一。介绍了原子吸收分光光度计测定重金属废水中Pb、Cd的原理,重点阐述了废水中Na的含量对仪器测定Pb、Cd结果的影响,并通过对比实验研究了在火焰原子吸收分光光度法测定Pb、Cd时Na含量及浓度的控制范围,初步了解Na含量对该方法的干扰影响程度。Flame atomic absorption spectrophotometry is one of the most important methods for the analysis and detection of the concentration of metal elements.The principle of determination of Pb and Cd in heavy metal waste water by atomic absorption spectrophotometer is introduced,and the influence of Na content in waste water on the results of determination of Pb and Cd is emphasized.The control range of Na content and concentration in determination of Pb and Cd by flame atomic absorption spectrophotometer is studied through comparative experiment,so as to understand the interference degree of Na content on this method.
