We developed the oxidation reaction of Cu(I) ion in aqueous hydrochloric solution by oxygen in a gas‐lift capillary bubble column. The method of gas‐liquid absorption with chemical reaction was used. Test data confirmed that the rate constant of the reaction is strongly affected by solution compositions, and that chloride ions induce an inhibition effect. The kinetical orders found are equal to 1 and 2 for oxygen and Cu(I) respectively. The influence of temperature on reaction rate constant showed the existence of a maximum value between 303 and 313K. The effect of gas‐liquid of gas‐liquid system on the liquid‐side mass transfer coefficient k L was also investigated.
