Abstract:

Lead-selective film electrodes with solid contact with membranes on the basis of niobates and vanadates of compositions Sr 2.75Pb 0.25La(VO 4) 3, Ba 3.8Pb 0.2Nb 2O 9, Ba 3.5Pb 0.5Nb 2O 9, Pb 3NiNb 2O 9, and Pb 2Nb 2O 7 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 Pb 3NiNb 2O 9 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. © Nauka/Interperiodica 2007.
