Abstract

In this paper, polyvinylpyrrolidone-stabilized Ag/Cu/Fe polymetallic composites were successfully prepared by liquid-phase reduction method and characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM) and Vibration magnetometer (VSM) detection means thatthe crystal structure of the material, surface morphology, Magnetic properties and group changes. The catalytic degradation of chlorinated phenolic organic pollutants, such as 2,4-dichlorophenolin water was studied initially discussed the Ag/Cu/Fe NPs removal of 2,4-dichlorophenol catalyticreduction mechanism and kinetic model. The results show that PVP has good stability to Ag/Cu/Fe NPs. The particle size of Ag/Cu/Fe modified by PVP is small, and it is uniformly dispersed inalcohol aqueous solution and cannot be easily agglomerated. Fast and efficient separation, with excellent recycling performance, PVP stabilized Ag/Cu/Fe NPs for 2,4-dichlorophenol catalyticdegradation has a good effect. The degradation of 2,4-dichlorophenol by Ag/Cu/Fe NPs accords with quasi-first-order kinetic model.
