The kinetics of absorption of oxygen in aqueous solutions of acidic chromous chloride and ammoniacal cuprous chloride were studied in a stirred cell. Both these reactions were found to be very fast and the theory of gas absorption accompanied by fast pseudo-m"' order reaction was used to analyse the

โฆ Synopsis
The rates of absorption of chlorine diluted with nitrogen into aqueous acidic solutions of ferrous chloride of various concentrations were measured at l&25,35 and 45ยฐC using a batlled agitated vessel operated batchwise. The experimental results were analysed with the chemical absorption theory based on the Ltvhue model.
The reaction was found to be second-order, i.e. first-order with respect to both chlorine and ferrous chloride. The reaction rate constants were calculated and correlated as a function of temperature and ionic strength of the solution.

## Abstract It was established that chlorine reacts with both water and hydroxyl ions. At a short reaction time when the pH was less than 3 the reversible reaction of chlorine and water controlled the absorption rate. From pH 3 to 10.5 the forward reaction predominated and yielded an apparent first
The absorption and reaction of oxygen in aqueous alkaline solutions of sodium dithionite has been experimentally investigated in a novel gas-liquid contactor. The novel gas-lift bubble column contactor was used to study the kinetics over wide ranges of reactant concentrations, temperature, and pH. T
