| Abstract: Amino-functionalized Fe3O4 magnetic material (NH2@nFe3O4) was prepared via a solvothermal method, followed by impregnation with Al(Ⅲ) phthalocyanine sulfonate (AlPcS). The characterization of material with Fourier transform infrared spectroscopy, diffuse reflectance, X-ray diffraction, scanning electron microscopy, transmission electron microscopy, and vibrating magnetometer show that AlPcS mainly combines with NH2@nFe3O4 through electrostatic interaction. The average particle size and saturation magnetization of AlPcS-NH2@nFe3O4 were 127 nm, and 75.3 emu·g-1, respectively. Under visible light and air, this functionalized magnetic material has high photosensitization activity for degradation of bisphenol A (BPA), an environmental endocrine disruptor in weak alkaline aqueous solution. The photosensitization activity of composite changed with the content of AlPcS, and 3.4%(w/w) AlPcS-NH2@nFe3O4 showed the best photosensitization activity. After 60 min of reaction, the degradation rate of 20.0 mg·L-1 BPA was up to 96%, and it still remained above 93% after ten-repeated use. The reaction mechanism was discussed by NaN3 quenching experiment. It is confirmed that 1O2 is the main active species in the photosensitization process. |
