A High Performance Ion Chromatographic (HPIC) method for the determination of nine components in Bayer liquors was reported.Formic, acetic, propionic, oxalic, succinic, glutaric anion, F -, Cl -, and SO 4 2-were separated and determined by High Performance Ion Chromatography with conductivity detector.The analytes were removed from Bayer liquor by using an ion-exchange resin column.The chromatographic separation was achieved with only one IonPac AS11-HC column thermostated at 30 °C.The precision results showed that the repeatability and reproducibility were <2.94 and <1.37%, respectively.The accuracy of the method was assessed by the recoveries ranging from 86.3 to 105.6 %.Under optimum conditions the detection limits ranged from 0.008 to 0.053 mg/l.
