%X An ion chromatographic method for determining chloride and trace anions, such as F-, Br-, I- and SO4(2-) in natural gas field water with high chloride concentration was studied. The separation of the anions was achieved on an IonPac AS11 column with NaOH as gradient eluent, and the detection was performed by a conductivity detection mode (self-regenerated suppression). The pre-treatment of the samples was through a filter of 0.45 micron and a Dionex OnGuard RP C18 column. The method is simple and useful, and has good linearity with correlation coefficients between 0.9994 and 0.9999. The recoveries of anions in the samples were between 98.4% and 102.1%.
