  • Apparatus and method for measuring dissolved halogens
    Patent number: 4440603
    Abstract: Liquids are monitored for dissolved halogens using amperometric detection based on the use of halogen specific electrodes of a conductive substrate on which is formed an adherent surface film of [Ti.sub.x (Ru, Ir).sub.1-x ]O.sub.2, wherein x=mole fraction .gtoreq.0 to <1, and (Ru, Ir) represents either ruthenium or iridium or mixtures thereof. The described electrodes resist corrosion and failure in extremely harsh environments, e.g., hot concentrated brine solutions.
