Absorption of atmospheric oxygen by agitated weakly alkaline solutions of surfactants

Absorption of atmospheric oxygen by agitated weakly alkaline solutions of surfactants Volumetric analysis of the decomposition kinetics of sodium hydroxymethylsulfinate was performed to study the absorption of atmospheric oxygen by surfactant solutions agitated in various modes at 353 K. The application of the Danchwerts model of surface renewal made it possible to evaluate the contribution made by changes in driving forces in the stages of O2 absorption and solvation to the overall effect of accelerated gas absorption. The intensifying influence of surfactants on the process of oxygen absorption, manifested in an immobile fluid and at slow solution agitation rates, is eliminated by the oppositely directed changes in the mass transfer and solubility of oxygen at the phase boundary in the transition and turbulent flow modes. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Applied Chemistry Springer Journals
