The objective of this work is to modelling a new separation technique based on the removal of antibiotics such as amoxicillin and ampicillin produced by antibiotical company Saidal Médéa (Algeria) from pharmaceutical effluents using biosurfactants and commercial surfactants. The kinetic distribution of amoxicillin and ampicillin between the two phases was modelled in order to well understand the mechanism governing the direct transfer of antibiotics from the aqueous phase to the micellar phase. The results were interpreted in terms of a two-film theory for flat interface. The model of the kinetic transfer developed in this study provides excellent predictions. A very good correlation between predicted and experimental values was found : R2 = 0.98 for the sorption onto biosurfactant and R2 = 0.99 onto a synthetic surfactant. The model coefficients were used to estimate the overall combined mass transfer coefficient and the individual mass transfer coefficients.
