摘要
采用火焰原子吸收分光光度法测定生活饮用水中钠的含量.根据本地区自来水中钠的含量,选择出最佳灵敏线应用于本机分析试验,获得满意效果.检出限0.20 mg/L,相对标准偏差0.035%,回收率为99.90%~103.4%.该方法简单易行,准确度高,适用于含常量浓度钠的天然水样测定.
Flame atomic absorption spectrophotometry was employed to determine the content of sodium in drinking water samples.According to sodium content in tap water in local area,the best sensitive line was selected and applied to our analysis test,and satisfactory results were obtained: detection limit for sodium was 0.20 mg/L;relative Standard Deviation was 0.035% and recoveries ranged from 99.90% to 103.45%.This method was easy,with high accuracy,and can be applied to the test of natural water sample with constant sodium content.
