玻璃和玻璃器皿 萃取溶液的分析 第2部分:用火焰光谱法测定氧化钠和氧化钾

[中文适用范围]： 该方法的原理是将提取溶液喷入发射或吸收光谱仪的燃烧器火焰中，如有必要，添加光谱化学缓冲溶液，或喷入过滤火焰光谱仪的火焰中，而不添加这种溶液。 对于 FES 和 FAAS，分别使用 589,0 nm 和 766,5 nm 处的谱线，并与参考溶液的测量结果进行比较；对于火焰滤光片光谱仪，使用特定的滤光片。 测量钠和钾的浓度，以它们的氧化物 NaO 和 KO 表示。 适用于分析从任何种类的玻璃或玻璃器皿中获得的提取液。 [外文原描述]： The principle of the method specified is spraying the extract solution into the flame of the burner of an emission or absorption spectrometer, if necessary with the addition of a spectrochemical buffer solution, or into the flame of a filter flame spectrometer without this addition. For FES and FAAS, the lines at 589,0 nm and 766,5 nm, respectively, are used and compared with the measurements of reference solutions, for a flame filter spectrometer, the specific filters are used. Measures the concentrations of sodium and potassium, expressed as their oxides Na 2 O and K 2 O. Applies to the analysis of extract solutions obtained from any kind of glass or glassware.
