摘要
选择HP 1大口径厚液膜通用型熔融石英毛细管柱(30m×0.53mm×2.65μm),ECD检测器,吹扫 捕集法富集样品,研究了测定10种挥发性卤代烃的最佳色谱条件。结果表明,水样体积为5.00ml时,标准偏差<0.07μg·L-1,RSD<4.0%,加标回收率为94.0%～107.0%,10种物质的检出限在0.07～0.19μg·L-1之间。方法用于河水样品中的组分测定,结果满意。
Optimum conditions for the determination of 10 volalite halogenated hydrocarbons by the capillary GC were studied in detail. The HP-1 fused silica capillary column (30m×0.53mm×2.65μm) of general usage and with large-bore thick liquid membrane, and ECD detector were used in the analysis. The volatile halogenated hydrocarbons in water were purged with nitrogen and trapped with the trap Ⅰ (VOCARB 4000). As 5ml of the water sample were taken, the standard deviations and the RSD′s ( n =6) found were smaller than 0.07μg·L^(-1) and less than 4.0% respectively. Recoveries obtained are in the range of 94.0%～107.0%. The detection limits of 10 volatile halogenated hydrocarbons were found to be in the range of 0.07～0.19μg·L^(-1). Satisfactory results were obtained in the analysis of river water sample by this method.
