Xiao, X. Jiang, X. Chen] An ion chromatographic (IC) method for the determination of six organic acids and three inorganic anions in Bayer liquors was proposed. Formic, acetic, propionic, oxalic, succinic, glutaric acid, F−, Cl−, and SO 4 2− were separated and determined within 33 min. For the first time, repeatability, reproducibility, and recoveries for the determination of these acids in Bayer liquors were estimated. The analytes were removed from a 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 relative standard deviations of the repeatability and reproducibility were <2.94 and <1.37%, respectively. The accuracy of the method was confirmed with an average recovery ranging between 86.3 and 105.6%. Under optimum conditions the detection limits ranged from 0.008 to 0.053 mg/L.
