摘要
实验的主要目的是对火焰原子吸收光谱法测定饮用水中铜和锶的方法进行研究。其中对火焰原子吸收光谱法测定锶的两种方法均进行了研究。在选定的最佳仪器条件下,测定铜、锶(方法 1)和锶(方法 2)RSD分别为0.65%、2.67%、1.01%。饮用水中铜、锶(方法 1)和锶(方法2)的回收率分别为95.00%、95.00%、91.00%。实验表明,该法操作简单、测试快速、结果准确稳定。
The method for the determination of copper and strontium in drinking water by flame atomic absorption spectrophotometry (FAAS) was studied in this paper. Under the optimum experimental conditions, the RSD results of copper, strontium (EDTA) and strontium (La) were respectively 0. 65% , 2.67% , 1.01%. The recoveries of copper, strontium (EDTA) and strontium (La) were respectively 95.00% , 95.00%, 91.00%. The method had simple operation, high- speed determining and stable results.
