| 摘 要： | 提出了使用电感耦合等离子体原子发射光谱法(ICP-AES)测定Mg元素的方法。采用硝酸、盐酸溶解样品,用硝酸和盐酸的混合酸作为测定介质,在选定的仪器条件下直接测定Mg元素的检出限为0.0044μg/mL,相对标准偏差RSD(n=6)为0.49%～0.60%,样品加标回收率在94.0%～102.0%之间。经对比试验证明,电感耦合等离子体原子发射光谱法(ICP-AES)测定无定形硼粉中Mg的测定值与美国军用标准重量法测定值一致。

| Abstract: | A new analytical method was proposed to determine magnesium in amorphous boron powder by inductively coupled plasma atomic emission spectrometry(ICP-AES).The samples was firstly dissolved in nitric-hydrochloric acid and then determined by ICP-AES under optimal instrument conditions with nitric-hydrochloric acid as the testing medium.The detection limit for Mg was 0.0044 μg/mL and the relative standard deviations(RSD,n=6) were 0.49 %~0.60%.The recoveries for testing the spiked samples were between 94.0%~102.0%.The comparison tests showed that the values determined by ICP-AES were consistent with those by the standard gravimetric method used by US army. |
