ICP-AES法测定高碳高铬蓖条中的锰、铝和钛

Determination of Mn,Al and Ti in High Carbon High Chromium Steel Strip by ICP AES

本文应用 ICP- AES法同时测定高碳高铬蓖条中锰、铝和钛。用稀硫酸分解样品 ,滴加硝酸破坏碳化物 ,水溶解盐类。本方法简单、快速、测定结果准确。相对标准偏差 RSD<2 .2 4 %。

Determination of Mn,Al and Ti in high carbon high chromium steel strip by ICP\|AES is described.The sample is decomposed with H 2SO 4(1+1),and the carbide is destroyed by HNO 3,then the salt is dissolved with distilled water.This method is simple,rapid and the results are accurate.The relative standard deviations are less than 2.24%.
