ICP-AES直读光谱仪具有多元素同时测定、线性范围宽、分析速度快等优点。方法简便、快速,各元素间没有明显干扰。本方法用HCl和HNO3分解试样,加入HF和HClO4冒烟除去SiO2的干扰后,用国家一级标准物质GBWO7310、GBWO7312、NGS-01、NGS-02等对方法进行验证,结果满意。
ICP-AES direct-reading spectrometer has the advantages of simultaneous determination of multiple elements, wide linear range and fast analysis. Method is simple, fast, no significant interference between the elements. The method decomposes the sample with HCl and HNO3, and adds HF and HClO4 to eliminate the interference of SiO2 after smoking, and then verifies the method with GBWO7310, GBWO7312, NGS-01, NGS-02 and other national standard materials. The results are satisfactory.
