顺序等离子体光谱技术测定煤飞灰中常量,少量和微量元素

本文采用顺序等离子体光谱技术测定煤飞灰中主要成份（Ｃａ、Ｍｇ、Ｆｅ、Ａｌ、Ｓｉ、Ｎａ、Ｋ、Ｔｉ）及微量成份（Ｃｕ、Ｓｃ、Ｖ、Ｎｉ、Ｂｅ、Ｍｎ）。用扫描光谱法研究了分析线的选择和光谱背景的扣除。试样用密封罐混酸溶解。测定煤飞灰标准样品ＮＢＳ１６３３ａ的结果与标准值一致。方法用于测定新制备的煤飞灰标准参考物。

Determination of Major Minor and Trace Elements in Coal Fly Ash by Sequential ICP Spectrometer

In this article, major elements(Fe,Ca,Mg ,Si,Na,K,AI,Ti) and trace elements(Cu ,Sc,V,Be,Mn,Ni) in coal fiy ash were determined by sequential ICP spectrometer. The spectral interferents and line seletion were investigated with spectrum scan. The ash samples were dissolved in the mixture of nitric acid, perchloric and hydrofluoric acid. The results argree with certifiml values for determination of NBS 1633A coal fly ash. The method have been employed in comparison of new standard referenee material of coal fiy ash.
