中文摘要:
      采用液液萃取处理水样,用气相色谱-串联质谱法测定样品中五氯酚及其钠盐,通过优化测定条件,使方法在100 μg/L~500 μg/L范围内线性良好。检出限和定量限分别为100 μg/L和500 μg/L,空白水样五氯酚钠3个质量浓度水平的加标回收率为898%~984%,5次平行试验测定结果的RSD为55%~107%。
英文摘要:
      A method of liquid liquid extraction GC MS/MS was established for the determination of pentachlorophenol and sodium pentachlorophenate in water. By optimizing the determination conditions, the method had good linearity in the range of 1.00 μg/L to 500 μg/L. The detection limit and the limit of quantization were 1.00 μg/L and 5.00 μg/L, respectively. The recoveries of 〖JP2〗blank samples spiked with three concentration levels of sodium pentachlorophenate ranged from 89.8% to 98.4%, and the RSDs ranged from 5.5% to 10.7%
