Abstract :
A three-dimensional magnetic polymer aerogel (3D MPA) was prepared by a facile filler-loaded networks method, followed by a vacuum freeze-drying process and has been used for the first time to remove diclofenac sodium (DS) from aqueous solutions. The sorbent was characterized by X-ray diffraction (XRD) analysis, Fourier transform infrared (FT-IR) spectroscopy, field emission scanning electron microscopy (FESEM), and vibrating sampling magnetizer (VSM). The effect of factors on adsorption, including initial DS concentration, contact time, and temperature was studied. Also, the adsorption equilibrium was represented with Langmuir, Freundlich and Temkin isotherm models. The sorption of DS to 3D MPA agreed well to the Temkin and Langmuir adsorption models with the maximum adsorption capacity of 256.41 mg g−1. The excellent removal efficiency (86%) at room temperature indicated that 3D MPA has significant potential for the removal of DS from pharmaceutical wastewaters.
