英文摘要In the present paper, the authors investigated the adsorption of cadmium on magnetic Levextrel resin containing about 352 mg g(-1) Cyanex 272 (C272) as adsorbent. Magnetic Levextrel resin (mPst-DVB-C272) was synthesized through adding Cyanex 272 and oleic acid-coated magnetite nanoparticles directly to the mixture of styrene (st) and divinylbenzene (DVB) monomers during the bead polymerization. It is a new method for preparing magnetic Levextrel resins with less organic solvents and less steps MPst-DVBC272 was characterized with scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), thermal gravity (TG) and differential thermal gravity (DTG), and vibrating sample magnetometry (VSM). Then mPst-DVB-C272 was applied to remove cadmium. The effects of pH, initial Cd(II) concentration, and contact time on Cd(II) removal were investigated in batch experiments. The optimized pH value for the Cd(II) adsorption was 6.5. The maximum adsorption capacity was 18.77 mg g(-1) for mPst-DVB-C272. The adsorption reached equilibrium within 90 min and the experimental data fit the pseudo-second-order model. (C) 2021 Elsevier B.V. All rights reserved.
