Abstract An Ion Chromatographic (IC) method for the determination of six organic acids and three inorganic anions in alkaline solutions was reported. Formic, acetic, propionic, oxalic, succinic, glutaric acid, F ‐ , Cl ‐ , and SO 4 2‐ were separated and determined in 33 min. 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. Organic acids and inorganic anions were detected with a suppressed conductance detector. 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.
