摘　　要：采用高温燃烧水解煤样-超纯水吸收装置,建立了高温燃烧水解-淋洗液在线发生离子色谱法同时测定煤中氟和氯的分析方法。系统、全面地考察了测定方法的影响因素,确定了最优高温燃烧水解预处理煤样和离子色谱法条件,并将该方法推广应用于飞灰、土壤和岩石的氟和氯含量检测,实验测定值与标准物质真实值误差能满足测定要求。Using high temperature combustion hydrolyzing coal sample and ultra-pure water absorption equipment,the method of high temperature combustion hydrolysis-ion chromatography with on-line eluent generator is established,which can determine fluorine and chlorine in coal at the same time.The main affecting factors are investigated,and the optimum detecting conditions of high temperature combustion hydrolysis preprocessing coal sample and ion chromatography are determined.The method can also be extended to measure fluorine and chlorine in fly ash,soil and rock,since the errors between the testing values and the real values of standard material are very little and meet the determination requirements.
