Abstract: An uncertainty evaluation method for fluoride determination in karst underground water by ion chromatography detection technology was proposed.Usingcontinuous propagation model of uncertainty,the fluoride measurement uncertainty was evaluated.The double-error regression was used in the process of standardcurve fitting.Based on the quantitative analysis of each uncertainty componentduring experimental results,the standard uncertainty model for sulfate determination results was obtained.The main sources of measurement uncertainty came from sub-uncertainties of calibration solutions,calibration curve fitting and measurements process.

Key words: double-error regression, uncertainty, ion chromatography, fluoride
