摘要：Iron-manganese silicate polymer (IMSP) was synthesized in the laboratory and characterized by using X-ray diffraction (XRD), scanning electron microscope (SEM), energy dispersive X-ray spectroscopy (EDX), Fourier transformation infrared (FT-IR) and Brunauer-Emmett-Teller (BET). The mesopores and amorphous sample had nanorods structure, and on the surface was contained with abundant of surface hydroxyl groups. The catalytic activity of IMSP was investigated in terms of p-chloronitrobenzene (pCNB) and TOC removal. Ozonation catalysed by IMSP exhibited extraordinarily high catalytic performance over other studied processes. In the IMSP-catalytic ozonation process, 99.5 % conversion of pCNB and 50.7 % TOC was achieved in 15 min. Ozone dosage and catalyst dosage exert a positive influence on the removal rate of the pCNB. And the initial water pH of 7.0 ± 0.1 (the solution pH was close to the point of zero charge of IMSP) achieved the highest pCNB removal among all the tested conditions.
