| 摘 要： | 讨论使用电感耦合等离子体发射光谱法测定水样中si、Fe、Na时，四种水样前处理方法对测试结果的影响。提出采用HNO3^-HF体系微波消解、H3BO3掩蔽HF的方法前处理水样，用等离子体发射光谱法可同时准确快速地测定水中Si、Fe、Na三种元素的含量。5次测定的相对标准偏差小于4％，加标回收率为89．2％-106％。

| Abstract: | Simultaneous determination of Si,Fe and Na in water samples by inductively coupled plasma optical emission spectrometry was established.Four sample pretreatment methods were discussed and microwave digestion method with HNO_3-HF system was recommended.Boric acid is used to eliminate the interference effect from hydrofluoric acid.Recoveries of the method for these elements were 89.2%~106% with precision of less than 4%RSD(n=5). |
