摘　　要：综述了近年来国内外煤中痕量溴测定方法的研究进展,介绍了间接分析法和直接分析法的基本特点和原理。间接分析法是先用高温热水解法、碱熔法或微波处理法等消解煤样品,使煤中溴进入溶液中,再用离子色谱法、电感耦合等离子体质谱法等技术测定煤消解液中溴的含量。直接分析法是用X射线荧光光谱法或中子活化法直接测定固体煤中溴的含量。对各种测试方法的适用性、存在问题及发展方向进行了比较和评述。Recent progress of analytical methods for the determination of trace bromine in coal samples,including direct and indirect methods,were summarized in this paper.In indirect analytical method,coal sample was digested with high temperature hydrolysis,alkali-fusion or microwave digestion and then the bromine in sample solution was determined by ion chromatography（IC） or inductively coupled plasma-mass spectrometry（ICP-MS）.In direct analytical method,X-ray fluorescence spectrometry（XRF） and neutron activation analysis（NAA） are used to directly determine the bromine in coal samples.The basic characteristics and theory of each method are introduced.The applicability,existent problems and further development of the methods are also discussed.
