摘要
The potentiometric determination of fluoride with the use of an DKOM-F ion-selective electrode in red muds (waste of aluminum production) is described. The accuracy of ionometric determination of fluorine is estimated. The results are supported by the "added-found" method and the method of varying the sample weight, as well as by a comparison with the results obtained by an independent procedure.
