In this paper,the hazards and content range of fluorine and chlorine in coal are discussed.the distribution range of fluorine content in Tianshui City is 20pg/g～197μg/g.The chlorine content ranges from 0.003％to 0.139％.At the same time,the pretreatment method and measurement method of fluorine and chlorine were studied.Finally,it was found that the high temperature combustion hydrolyzation-ion chromatography method is suitable for the rapid detection of fluorine and chlorine in coal.Compared with the international standard,this method has high sensitivity,good repeatability and reproducibility,it can rapidly detect fluorine and chlorine in coal at the same time,which can greatly improve the detection efficiency.Suitable for daily laboratory inspection and testing.
