Özet
In this work, the diffusion of oxygen in solutions of alkyl (C13-15) benzyldimethyl ammonium chloride (ABDAC), nonylphenol (9) ethoxylate (NP9EO) and their mixture was investigated. The variation of oxygen concentration in ABDAC solution was found to be linear. The deviation from the linearity observed in NP9EO solutions was attributed to the trapping of oxygen molecules in the interstices of the coils of ethoxylate chains. Apparent diffusion coefficients of oxygen in the solutions were calculated analytically and numerically. In surfactant solutions, the diffusion coefficients passed through a minimum. The rigidity of the monolayer was found to be the predominant effect in the reduction of the transfer rate.
