摘要
本文提出了用ICP-AES法直接测定钢中铌的方法。分析时,所配铌标准溶液的硫酸酸度应与样品保持一致,否则测定结果偏低。此方法用于多种基体的钢中铌的测定,获得满意结果。
In this paper, direct determination method for Nb in steel by ICP-AES has been Studied. in analysis, the sulphuric acid acidity of standard solution should be identical with sample solution, otherwise the result determined will show a lower value. this method has been used to determine Nb in different steel samples and the results are satis factory.
