| Abstract: | In this paper,the High AlkaliFusion/Fluorine IonSelective Electrode Method was used for measurement of fluoride concentration in coals.The factors influencing the measurement process were researched and discussed.In addition,the distribution regularity of fluorine in various coal was reported.The results showed that the FZSEM have high degree of accuracy,small error and is convenient,fast in measurement.They are also of significance for selection of coal and retention of fluorine during the coal combustion. |
