摘　　要：首次建立了同时测定银精矿中氟和氯的离子色谱法。实验采用水蒸气蒸馏的方法提取银精矿样品中的氟和氯,研究了硫酸浓度、蒸馏温度、蒸馏时间等因素对氟和氯测定的影响。在最优条件下,氟和氯的平均加标回收率为95.1%~102.7%,相对标准偏差为1.92%~2.47%。该方法杂质干扰小、回收率好、重现性好,能够对银精矿中氟和氯进行准确的定量分析。A new method has been firstly developed for the simultaneous determination of fluorine and chlorine in silver concentrate by ion chromatography(IC).The test extracts fluorine and chlorine in silver concentrate sample by the method of steam distillation.The test researches the effects of vitriol concentration,distillation temperature,distillation time and so on on the determination of fluorine and chlorine.Under the optimumcondition,the average recover-ies of fluorine and chlorine spiked in silver concentrates samples are in th erange of 95.1%~102.7%,and the relative standard deviations are 1.92%~2.47%.The method shows little interferences,good recovery and repeatability.It is suitable for the simultaneous determination of fluorine and chlorine in silver concentrate samples.
