摘　　要：采用离子色谱法测定油田水中的氟、氯、溴、亚硝酸根和硫酸根的含量。以碳酸钠为流动相 ,用IonPacAS9 HC分析柱分离 ,分离效果理想 ,灵敏度较高。F-,Cl-,Br-,NO-2 和SO2 -4的检测限分别为 0 .0 1mg/L ,0 .0 2mg/L ,0 .0 3mg/L ,0 .0 1mg/L ,0 .0 2mg/L ,具有良好的线性和重现性。对油田水样品进行测定 ,其结果与化学法分析结果对比 。An ion chromatograph system for the determination of F -,Cl -,Br -,NO - 2,SO 2- 4 in oil field water was described. The mobile phase was sodium carbonate. The analytical column was IonPac AS9 HC. The detection limits of general anions were F -0.01mg/L, Cl -0.02mg/L, Br -0.03mg/L, NO - 20.01mg/L, SO 2- 40.02mg/L., respectively. Experiment results showed that linear relationship and repeatability were good. This method was used to determine general anions in oil field water, and the result coincided with the chemical analytical method very well. The method was simple, rapid, reliable and inexpensive.
