A Study of the Effects of Surface Active Materials on Oxygen Transfer

Abstract

<p> The effect of surface active on the rate of gas absorption into water was investigated. Pure oxygen was absorbed into quiescent de-gasified distilled water through-adsorbed monomolecular films of alkylbenzene Sulphonate (ABS) or sodium lauryl sulphate (NaLS).</p> <p> The rate of absorption was characterized by effective diffusivity as measured in detergent solutions up to 20 mg/1 and temperatures between 10 and 30°C.</p> <p> Gas transfer mechanistic models plus physical and chemical properties of surface films were reviewed in order to understand the fundamental processes of interfacial interference which would account for anomolies in results reported in the literature.</p>
