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.
