摘　　要：采用氧弹燃烧-离子色谱法,建立优化的实验条件,测定有机光电材料NPB中的氯离子的含量。以氧弹对有机光电材料NPB试样进行燃烧,4.5 mM Na2CO3/0.8 mM NaHCO3为吸收液进行吸收,以Dionex IonPac AS23柱,4.5 mM Na2CO3/0.8 mM NaHCO3等度淋洗,流速为1.0 mL/min,经离子色谱分离测定有机光电材料NPB中的氯的含量。利用该方法对有机光电材料NPB中的氯进行测定,线性相关系数为0.9999,平均加标回收率为94%~110%,相对标准偏差为5.15%~5.85%。The determination method of chlorine in organic photoelectric material NPB by oxygen bomb combustion with ion chromatography is adopted with optimized experimental conditions.In this experiment,the sample organic photoelectric material NPB was combusted with oxygen bomb,and 4.5 mM Na2CO3/0.8 mM NaHCO3 was used as the absorption solution.All samples were separated at Dionex Ion Pac AS23 column with mobile phase of 4.5mM Na2CO3/0.8 mM NaHCO3 at flow rate of 1.0 mL/min.The proposed method was used to determinate the chlorine in organic photoelectric material NPB samples,the correlation coefficient was 0.9999,the recoveries of anions were in the range of 94%~110%,and the relative standard deviations of chlorine were 5.15%~5.85%.
