摘要
依据毛细柱气相色谱法(《水和废水监测分析方法》第四版、GB/T13192-1991、EPA8141B),采用二氯甲烷作为萃取剂,在中性条件下,萃取水中的有机磷农药,用带火焰光度检测器(FPD)的毛细管气相色谱仪对其测量不确定度进行评定。评定结果为有机磷农药(以敌敌畏为例)的不确定度(0.0448±0.0048)mg/L,k=2。
On the basis of capillary column gas chromatography Water and Wastewater Monitoring Analysis Method the fourth edition, GB/TI3192- 1991, EPAS141B, using methylene chloride as extracting agent, under neutral condition, the organophosphorus pesticides in the water were extracted and the uncertainty of measurement was evaluated with FPD capillary column gas chromatography. The result of uncertainty for organophosphorus pesticide （DDVP） was of （0. 0448 ± 0, 0048 ） mg/L, k = 2.
