Analyzing the 13 C-DOC in high-salinity water remains challenging due to significant differences in interfering ions and analyte concentrations.In this study, halide interference was eliminated using an AgF solution to generate AgCl precipitate, and the 13 C-DOC was measured using a GasBench Plus preparation device coupled with isotope ratio mass spectrometry (IRMS), establishing an accurate and sensitive method to determine 13 C-DOC in high-salinity water samples.The external accuracy of the me
