| Abstract: | Brief introduction about the determination methods of trace element fluorine in coal.Indirect methods:alkali fusion/ion chromatography or fluoride ion selective electrode (ISE) method;high frequency induction furnace/ISE method;Oxygen bomb combustion/ISE method and pyrohydrolysis/ISE method.Direct methods:spectroscopic method,e.g. proton induced gamma ray emission (PIGME) method;mass spectrocopic method,e.g. spark source mass spectrometry (SSMS) method.The applicability and existent problems were particularly compared,analyzed and discussed in order to helping analysts to be more critical about the method they use.In addition,further investigation on the determination methods of fluorine in coal were suggested. |
