To develop a novel magnetic adsorbent for the removal of endocrine-disrupting chemicals, mesoporous magnetic clusters (MMCs) functionalized with beta-cyclodextrin (beta-CD), henceforth denoted CD-MG, were prepared by a facile chemical strategy and were applied to bisphenol A (BPA) removal for the first time. Fourier-transform infrared spectroscopy and thermogravimetric analysis revealed that beta-CD was successfully linked to the MMC surfaces. X-ray diffraction, field emission scanning electron microscopy, and high-resolution transmission electron microscopy confirmed that the morphologies and crystal structures of the MMCs were well preserved in CD-MG. A pseudo-second-order kinetic model and Langmuir isotherm model were used to describe the BPA adsorption behavior of CD-MG. The kinetic model yielded a BPA adsorption rate constant of 0.0367 g mg(-1) min(-1) , while the isotherm model yielded a maximum BPA adsorption capacity of 52.7 mg g(-1). Furthermore, CD-MG exhibited a good recovery efficiency of 84.5% in the reusability tests, even after four cycles. The fast adsorption kinetics, high adsorption capacity, and good recovery efficiency indicated that CD-MG could be an effective magnetic adsorbent for the removal of endocrine-disrupting chemicals.
