Abstract:

Lead-selective film electrodes with solid contact with membranes on the basis of niobates and vanadates of compositions Sr2.75Pb0.25La(VO4)(3), Ba-3.8 Pb0.2Nb2O9, Ba3.5Pb0.5Nb2O9, Pb3NiNb2O9, and Pb2Nb2O7 are constructed and studied. Basic electrochemical characteristics of ion-selective electrodes, such as linearity region and steepness of the electrode function, working pH interval, type of electrode function, and reproducibility are determined. The electrode with a membrane on the basis of Pb3NiNb2O9 is tested and recommended as an indicator in the method of potentiostatic titration. The optimum titrant for assaying ions of lead(II) in solution is potassium chromate.
