| Abstract: | Sulfate is one of the main indicators of "drinking water health standards".The scientific and accurate determination of the results is important to the evaluation of water quality and protection of people's health.According to CNAS-GL06 "the guide of uncertainty evaluation in the chemical analysis",through sampling and analysis,uncertainty evaluation of sulfate in water had been assessed by ion chromatography.The results showed that the concentration of sulfate in water was 49.683 mg/L and expanded uncertainty was 1.364 mg/L.The main factors affecting determination uncertainty of sulfate came from the introduction of fitting curve,the repetition of measurement and the process of using pipette. |
