摘要
本文以Ｎａ２Ｏ２熔样、ＨＮＯ３酸化，用ＩＣＰ一ＡＥＳ测定了高碳铬铁中３．０％以下的硅量。本法简单、快速、干扰少、线性好，精密度与准确度均令人满意。
This paper describes a simple and rapid test method for the determination of silicon content under 3.0 percent in high carbon ferrochrome.It is determined with ICP-AES after melting the sample with sodium peroxide and acidizing by nitric acid. The method has less interference and better linearity, as well as satisfactory precision and accuracy.
