ICP—AES测定铝合金中的硅、锰、镁、铬、铜、镍、铁、钛、锌

THE DETERMINATION OF Si、Mn、Mg、 Cr、Cu、Ni、Fe、Ti、Zn IN ALUMINUM ALLOY BY ICP-AES

采用氢氧化钠强碱溶样,硝酸酸化,电感耦合等离子发射光谱同时测定铝合金中的硅、锰、镁、铬、铜、镍、铁、钛、锌元素。经试验,该方法简单、快速,结果准确、可靠。

After sample of aluminum alloy was dissolved with sodium hydroxide and was acidified with nitric acid, the elements including Si, Mn, Mg, Cr, Cu, Ni, Fe, Ti, Zn were determined by ICP--AES. The results showed that, the method was simple, quick, exact and reliable.
