  • Method for measuring dissolved oxygen of oxygen water
    Patent number: 10018605
    Abstract: A method for measuring an amount of dissolved oxygen contained in a liquid sample, including the steps of: (1) adding a deoxygenating amino compound to a liquid sample to prepare the liquid sample having a predetermined concentration of the deoxygenating amino compound; (2) after Step (1), heating the liquid sample containing the deoxygenating amino compound at a temperature of 80° C. or more; (3) after Step (2), measuring the concentration of the deoxygenating amino compound contained in the liquid sample; and (4) calculating the amount of the dissolved oxygen contained in the liquid sample in Step (1) from the amount of the reacted deoxygenating amino compound by comparing the concentration of the deoxygenating amino compound measured in Step (3) and the concentration of the deoxygenating amino compound measured in Step (1).
