摘要
运用离子色谱法对硫酸盐的标准样品和实际样品进行研究分析,通过全国多家实验室的大量监测数据,得出了当前常用的精密度及准确度方面质量控制指标的建议值。研究表明:在0.5~230mg/L浓度范围内,标准样品的RSD≤3.0%,RSD’≤7.0%,RE≤±15%。实际样品0.5~210mg/L。RD≤4.0%,加标回收率范围为90%-115%。
Both standard sample and real sample of sulfate were analyzed by ion chromatography method. The recommendations on quality control indexes based on lots of monitoring datum from many national labs were put forward. The results showed that the RSD of the standard sample is less than 3.0%, with less than 7.0% of RSD' and less than 15% of RE when in the concentration of 0. 5mg/L to 230mg/L. The RD of the real sample is less than 4.0% with recoveries of 90% to 115% when in the concentration of 0. 5mg/L to 210mg/L.
