| 摘 要： | 研究了原子荧光法测定水中汞的质量控制指标，提出精密度和准确度质量控制指标，具有广泛指导意义。全国东、西、中部共16个省份的62家实验室参加测定工作。研究结果为：标准样品浓度为5．0～15．Oμg／L时，RSD≤5．0％，RSD’≤10．0％，RE≤±10．0％；实际样品浓度为0．005—6μg／L时，RD≤20．0％；空白加标回收率80％-110％，标准样品和实际样品加标的回收率90％～110％。

| Abstract: | The quality control indices on accuracy and precision on mercury monitoring by atomic fluorescence method were researched. There were 62 labs in the east and west and middle part of China involved in. The results indicated that the RSD was less than 5. 0% with less than 10. 0% of RE and less than 10, 0% of RSD＇when the real sample concentration was 5. 0 - 15. 0μg/L. However, the RD was less than 20. 0% with 80% - 110% of blank recovery of standard addition when the standard sample concentration was 0. 005 - 6μg/L, and the recovery of standard addition of real sample and standard sample was 80% - 110%. |
