| 摘 要： | 通过对全国9个省份82家实验室监测数据的分析,研究确定了石墨炉原子吸收法测定水中铅的质量控制指标。建议控制值为：标准样品室内相对标准偏差（RSD）≤5.0%,实际样品相对偏差（RD）≤30.0%,标准样品室间相对标准偏差（RSD’）≤10%,标准样品相对误差（RE）≤±8.0%,加标回收率范围为90%～115%,同时还对方法的重复性和再现性指标进行了验证性研究。

| Abstract: | On statistic result of monitoring data from Chinese 82 laboratories,quality control index was identified for determination of Lead in water by the graphite furnace atomic absorption spectrometry.The laboratory quality control index for the method should be as fallow： relative standard deviation（RSD） of standard sample within laboratory ≤5.0%;relative deviation of samples（RD） ≤ 30.0%;relative standard deviation（RSD＇） of standard samples from interlaboratory ≤10%;relative error（RE） of standard sample ≤±8.0%;recovery between 90% and 115%.A test study was carried out to verify repeatability and reproducibility of the method. |
