MASS TRANSFER IN A LIQUID–LIQUID

Abstract. A liquid–liquid phase ozonation process for the removal of phenolic compounds from an aqueous solution using fluorinated organic solvents as the ozone carrier was studied. The experimental results showed that the oxidation of phenolic compounds by ozone is a mass transfer process accompanied by a surface reaction in the boundary layer of both the aqueous and the organic phase, whose role depends on the distribution coefficients and concentrations of reactants. The interfacial mass transfer is enhanced by the chemical reaction. Mass transfer coefficients, enhancement factors, and distribution coefficients of phenol, 4-methylphenol, 4-chlorophenol, and ozone were determined
