| 摘 要： | 采用固相萃取-高效液相色谱法测定水中呋喃丹浓度,对测量结果的不确定度进行了评定。根据《测量不确定度评定与表示(》JJF 1059-1999)中有关规定,建立呋喃丹不确定度分析数学模型。结果表明,该方法测量结果不确定度的主要来源为标准溶液的配制、定容和重复性测试,当水样中呋喃丹的浓度为0.03 mg/L时,扩展不确定度为0.0044 mg/L(k=2)。

| Abstract: | A method was developed for determining carbofuran in water by HPLC combining with solid-phase extraction and the measurement uncertainty was evaluated.A mathematical model for carbofuran uncertainty assessment was established according to Evaluation and Expression of Uncertainty in Measurement(JJF 1059-1999).The uncertainty of this method was mainly caused by preparation of working standards,dilution of standard solution and replicate injections.The expanded uncertainty was 0.004 4 mg/L as content of carbof... |
