摘要
建立了用电感耦合等离子体原子发射光谱(ICP-AES)法测定高纯铝中Fe、Cu、Mg、Zn、Ti的方法。详细讨论了基体元素和共存元素对分析元素的光谱干扰,以及盐酸用量的影响;选择了合适的分析谱线,同时得出了各元素的检出限。证明用基体匹配的方法在Fe 259.940nm、Cu 327.396nm、Mg279.079nm、Zn 213.856nm、Ti 334.941nm处可准确、可靠地测定高纯铝中含量范围在0.001%~0.01%的Fe、Cu、Mg、Zn、Ti元素。
The method for the determination of Fe, Cu, Mg, Zn and Ti in AES was established. The spectral interferences from matrix elements and effects of hydrochloric acid dosage on analysis results were investigated. The and the detection limits of the method were determined. It was found that th convenient. Ti 334. 941 from 0. 001 It was proved that using Fe 259. 940 nm,Cu 327. 396 nm,Mg nm spectral lines, Fe,Cu,Mg,Zn,Ti elements in high pure al high pure aluminum by ICPcoexistence elements and the analytical li is method is 279. 079 nm,Zn uminumin the co nes were selected fast, accurate and 213. 856 nm, and neentration range % to 0.01% can be measured accurately and reliably by matrix matching method
