摘要: A novel separation technique based on an aqueous surfactant extraction to remove organic contaminants from solutions was investigated. model developed regarding the kinetic partitioning of amoxicillin and mechanism governing forward transfer in a reverse micelle system. Results were interpreted terms two-film theory for flat interface. To confirm relevance technique, it applied elimination by adsorption anionic surfactant, sodium dodecyl sulfate. The effects various parameters such as contact time, pH, temperature, initial concentration sulfate investigated at agitation speed 350 rpm. percentage maximum capacity found be 87.7 % following optimal conditions: 4 mg/L, 40 min pH 4, 50 °C, 0.01 g/L concentration. results showed that pseudo-first-order provides most adequate correlation experimental data compared pseudo-second-order model. Three statistical functions used estimate error deviations between theoretically predicted values, including average relative deviation (ARED), sum squares errors (SSE), standard residuals (S res). that, both Freundlich equation provide best fit data. Adsorption isotherm appeared accurately described thermodynamic (∆G, ∆H, ∆S) process feasible, spontaneous, exothermic.
