In this article, a novel recyclable -cyclodextrins (-CDs)-based supramolecular adsorbent had been fabricated. With Fe3O4 magnetic nanoparticles as core, the adsorbent could be separated from water conveniently. Moreover, the hydrophobic -CDs caving had strong host-guest interaction with organic compounds to form complexes. With the pH value changing, the stable complexes would disassemble to recover the adsorbent. Fourier transform infrared analysis, X-ray diffraction measurement, transmission electron microscopy measurements, thermogravimetric analysis, and vibrating sample magnetometer analysis had been explored to confirm the structure and properties of supramolecular adsorbent. Congo red and Rhodamine B were used to characterize the adsorption capacity of adsorbent. By changing the parameters such as temperature, time, adsorbent dosage, and pH value indicated that the designed adsorbent could rapidly remove organic dyes from water with satisfactory removal effects and adsorbent recycling capacity.
