| 摘 要： | 通过全国17个省份69家实验室的监测数据分析，研究确定了原子吸收法测定水中锰的质量控制指标和重复性限、再现性限，建议控制值为：浓度在0。1～3mg／L范围内的标准样品，控制RSD≤4％，RSD≤10％，RD≤5％，RE≤±10％；浓度在0．01—25mg／L范围内的实际样品，控制RD≤7％；同时，建议加标回收率控制在90％～110％。

| Abstract: | On the basis of a large number of monitoring data from 69 laboratories of 17 provinces, we analyzed and determined the quality control index, repeatability ＇limit and reproducibility limit for determing the manganese in water by atomic absorption spectrometry. The control limit has been suggested as follows： for the standard sample with a concentration of 0. lmg/L -3mg/L, the control RSD ≤4%, the RSD≤10%, RD≤5%, RE≤± 10% ; for the standard sample with a concentration of 0. 01mg/L -25mg/L, control RD ≤7%. Meanwhile, the recovery rate was suggested to be between 90% and 110%. |
