A comparison method was used to determine a more effective reagent. It was shown that the speed and efficiency of the process increase with increasing reagent concentration. The initial oxygen concentration in water in this case depended on the temperature of the environment. The process was monitored with an oxygen meter by changing the oxygen concentration in a hermetically sealed container. At a temperature of 20°C, the oxygen binding process lasted for more than 60 minutes. With an increase in the concentration of iron (II) ions, greater efficiency was achieved than when using copper (I) ions.encomparison methodiron (II) sulfatecopper (I) oxidehydrazinecorrosionoxygen meterelectrochemical deoxidation methodsметод порівняннясульфат заліза (ІІ)оксид міді (І)гідразинкорозіякиснемірелектрохімічні методи знекисненняArticleС. 207-211https://doi.org/10.20535/EHS2710-3315.2025.3297250009-0004-9692-39300000-0001-6431-7128
