引言氟电极是除PH玻璃电极之外,应用最广泛的一种选择电极。氟电极法日益成为冶金和环保试样中测定氟的重要手段。国外早在1973年就已作为测定工业废水中氟的标准分析方法。近年来该法已被中美等国作为空气污染监测的指定方法或标准方法。以往的钍——偶氮砷I容量法,镧——茜素络合酮比色法基本上已被氟电极法所取代。
Introduction The fluorine electrode is the most widely used one except the glass electrode. Fluoride electrode method is increasingly becoming an important measure for the determination of fluorine in metallurgical and environmental samples. Abroad as early as 1973 has been used as a standard method for the determination of fluorine in industrial wastewater. In recent years, the law has been China and the United States and other countries as a designated method of air pollution monitoring or standard methods. In the past, the thorium-azo-arsenic I volumetric method and the lanthanum-alizarin complexed ketone colorimetric method have basically been replaced by the fluorine electrode method.
