A magnetic biosorbent was synthesized from rice straw (a biological waste) and magnetic particles of Fe3O4. The produced biosorbent, which was characterized by XRD, FE SEM, FTIR, and TGA experiments, was used for adsorption of two drug chemical components of Penicillin G and Amlodipine Besylate from aqueous solutions. Effects of various operating parameters such as adsorption temperature (10 to 70 °C), the dose of adsorbent (1 to 5 g/ L), contact time (30 to 360min), and pH of system (pH=4 to 11) on the adsorption efficiency were studied. The produced adsorbent can remove impurities with maximum adsorption efficiency of about 95% for Pen-G and 65% for AMB; therefore, it is a good adsorbent for removing pharmaceutical impurities from wastewater. Moreover, the produced biosorbent can easily separate from the solution by using an external magnetic field. Five isotherm models--linear adsorption model, Langmuir, Freundlich, Sips, and Toth--were used for describing the results; and based on Langmuir isotherm, the maximum adsorption capacity of the produced biosorbent is 164.7mg/g for Pen-G and 229mg/g for AMB. The adsorption kinetics was well fitted with the pseudo-first-order kinetic model, and it is shown that the adsorption is extremely in physical mode.
