水泥及其原料中氧化钾和氧化钠的分析方法有重量法、火焰光度法~([1-2])、原子吸收光谱法和X射线荧光分析法。重量法由于分析过程复杂繁琐,已经很少使用了。GB/T 176—2008测定水泥中氧化钾和氧化钠的方法为火焰光度法(基准法)和原子吸收光谱法(代用法)。火焰光度法需要用氨水和碳酸铵,以沉淀过滤的方式分离铁、铝、钙、镁离子干扰,分析过程长,易
Methods for the analysis of potassium oxide and sodium oxide in cement and its raw materials are gravimetric method, flame photometry ~ ([1-2]), atomic absorption spectrometry and X-ray fluorescence analysis. Gravimetric methods are rarely used due to the complexity and complexity of the analysis. Methods for the determination of potassium oxide and sodium oxide in cement are flame photometry (reference method) and atomic absorption spectrometry (alternative method). Flame photometric method requires the use of ammonia and ammonium carbonate, precipitation precipitation method to separate iron, aluminum, calcium, magnesium ions interference, the analysis of long, easy
