Makarov A.G., Razdobreev D.A., Sagida M.O. SENSORS PH ON THE BASIS CHALCOGENIDES OF IRONThe behavior the electrodes on the basis chalcogenides of iron of structure of FeS2, FeSe2 and FeTe2 at change of concentration of H3O+-ion in solution have been investigated. Shows the advantages and disadvantages of the electrodes in compari-son with commonly used glass electrode.Tilt of electrode functions in the range рН from 3 to 11 are defined. Describes practical application of the investigated elec-trodes for example titration hydrochloric, sulfuric and phosphoric acids.Key words: pH-sensors, electrometric titration, indicator electrodes, chalcogenides of iron.
