摘要
建立了采用顶空气相色谱技术测定过氯乙烯中残留氯苯含量的新方法。采用HP-5毛细管柱,FID检测器,以环己酮为溶剂,外标法定量。氯苯的线性回归方程为Y=1.635 1c-12.535 6,r=0.999 8,该方法测定结果的相对标准偏差为1.12%,平均加标回收率为98.24%(n=5),检出限为0.07μg/mL。
A new method for the determination of residual chlorobenzene in perchloroethylene by headspace gas chromatography was developed. The analysis was carried out with HP -5 capillary column and cyclohexanone as solvent. The external standard method was used for quantitative analysis. The linear equation was Y = 1. 635c - 12. 535 6 with correlation coefficient of 0.999 8. The RSD was 1.12% （ n = 6 ）, and the average recovery was 98.24% （ n = 5 ）. The detection limit was 0.07 μg/mL.
