由于 ICP 光源具有高温、高灵敏度、高精度、基体效应小等特点,近年被普逼认为是溶液分析的一种理想光源。试样经过简单处理之后,即可进行测定。本文探索了 ICP 光源某些特性,井用于发射光谱测定高钛渣及共氯化处理后铁渣中微量钪、镧、铈、钇、镱。研究了参数对灵敏度及基体效应的关系;盐酸、硝酸、硫酸酸度和 Due to its high temperature, high sensitivity, high precision and small matrix effect, ICP light sources are considered as ideal light sources for solution analysis in recent years. After a simple sample processing, can be measured. In this paper, some characteristics of ICP light source were explored and used to determine trace scandium, lanthanum, cerium, yttrium and ytterbium in iron slag after high-titanium slag and co-chlorination by emission spectrometry. The relationship between the parameters and sensitivity and matrix effect was studied. The acidity and acidity of hydrochloric acid, nitric acid and sulfuric acid were studied
