| Abstract: | 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. |
