摘    要:研究了离子色谱法测定水中氯化物质量控制指标,提出精密度和准确度的建议控制指标,具有广泛指导意义。全国东、西、中部共12个省份的53家实验室参加测定工作。研究结果为:在一定的浓度范围内,RSD1.0%,RSD≤5.0%,RE≤±5.0%;加标回收率为95.0%~115.0%;RD≤4.0%。

关 键 词:氯化物  离子色谱法  质量控制指标

Abstract:The quality control index on ion chromatography method for chloride in water was staled in this paper. The quality control index of precision and accuracy was proposed. 53 laboratories of 12 provinces participated the work of determination. The results showed that the RSD(within- laboratory relative standard deviation)control limit of standard samples was less than 1.0% in a certain concentration range, RSD'(inter- laboratory relative standard deviation)was less than 5.0 %. RE (the relative error)was controned within + 5.0%. The corresponding rates of samples could be ranged between 95.0% and 115.0%. RD(relative deviation) of standard samples and actual samples was controned within 4.0 %.
Keywords:chloride  ion chromatography method  The quality control index
