摘      要：Zinc and cerium carried zirconium phosphates （Zn-Ce/ZrPs） were prepared by exchanging zinc and cerium cations into sodium zirconium phosphate （NaZrP） through the ion-exchange method and characterized by X-ray diffraction（XRD）, energy dispersive X-ray spectroscopy （EDX） and scanning electron microscopy （SEM）. Furthermore, the specific surface area, zeta potential and antibacterial activity were tested. The results showed that Zn-Ce/ZrPs were with hexagonal crystal system, and the surface area of Zn-Ce/ZrPs increased much more than that of NaZrP. Zn-Ce/ZrPs showed obvious synergetic antibacterial effect, and have the potential to be used as antibacterial agents in environmental control.
