Bisphenol A (BPA), as an estrogen and endocrine disruptor, has been extensively found in groundwater, surface water and even drinking water. Herein, the magnetic D201-Fe 3 O 4 nanocomposite was successfully fabricated through in situ confinement of Fe 3 O 4 nanocrystalline in millimeter-sized D201 anion exchange resin. EDS elemental mapping of Fe, TEM image, XRD pattern and VSM magnetization curve of D201-Fe 3 O 4 nanocomposite revealed that the confined Fe 3 O 4 particles exhibited uniform distribution, nanosize, highly crystalline nature and ...
