    Comparison of the influence of iron and copper ions on water pollution processes at 20 ⁰C using hydrazine
    (КПІ ім. Ігоря Сікорського, 2025) Kosmyna, Mykola; Nosachova, Yuliia
    The kinetics of oxygen removal processes from water using gyrazine hydrate were studied. 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.

    Evaluation of the effectiveness of an amido-containing corrosion inhibitor in mineralized water-oil environments
    (КПІ ім. Ігоря Сікорського, 2025) Kosmyna, Mykola; Nosachova, Yuliia
    In this work, the effectiveness of inhibiting corrosion processes in mineralized water-oil media using a complexing amine-containing corrosion inhibitor was investigated in detail. The inhibition efficiency and corrosion rate were determined using the massometric method. According to the results of the experiments, it was found that the thiourea inhibitor was most effective in a medium with a NaCl concentration of 3 % and 10 % at pH 6-7 and doses of 10-50 mg/dm3. It was under such conditions that a significant decrease in the corrosion rate was observed compared to control samples without an inhibitor. In addition, the influence of temperature and acidity of the medium was an important factor. It was shown that at a weakly acidic pH and an elevated temperature of 80 °C, thiourea demonstrated increased inhibitory properties. At the same time, the results obtained indicate that the inhibitor is effective at lower temperatures. In particular, some of the experimental data demonstrate a high level of metal protection in environments with a fixed pH value at a temperature of 20 °C. After the conducted studies, it can be stated that the amino-containing inhibitor thiourea is a promising corrosion inhibitor for use in mineralized water-oil systems.
