Abstract

Antibiotics and pharmaceutical products cannot remove by conventional sewage treatment. In this work, an effective adsorbent Magnetic Multiwalled Carbon nanotube (MMWCNTs) was synthesized by co-precipitation of MWCNTs with Fe3O4 and used for removal of Amoxicillin from aqueous solutions. Response surface methodology on Central Composition Design (CCD) was applied for designing of experiments and building of models. Four factors including pH, adsorbent dose, time, and temperature were studied and used for the quadratic equation model to the prediction of optimal points.  By solvent the equation and considering the regression coefficient (R2 =0.99) the optimal points obtained as follows: pH =2.98; adsorbent dosage =2.16 g; time =22 min and temperature = 37.88 o C. Isotherm study of adsorption showed that the adsorption of amoxicillin onto MMWCNTs follows the Langmuir model. The maximum adsorption capacity is 215 mg g-1 obtained from Langmuir isotherm.
