Abstract

Abstract:

Ag-Fe₃O₄ functional nanomaterials were prepared by solvothermal method using AgNO₃ as raw material. The crystal structure, microstructure, spectral properties and pore characteristics of Ag-Fe₃O₄ nanomaterials were characterized by XRD, SEM, XPS, UV-vis, FTIR and nitrogen adsorption-desorption tests. Their adsorption performance for Cr（VI）in wastewater under different conditions was simulated. The results showed that the Ag-Fe₃O₄ nanomaterials prepared by solvothermal method hadanti-spinel structure and exhibitedhigh crystallinity. Ag had been successfully chemically loaded onto the surface of Fe₃O₄ through the interfacial Ag-O-Fe bonds, and the morphology was rough spherical particles. The sample loaded with 3% Ag exhibited the narrowest band gap of 2.77 eV and the longest absorption edge of 446 nm, with a maximum of specific surface area of 588.6 m²/g and a pore volume of 0.418 cm³/g. The loading of Ag significantly enhanced the performance of Fe₃O₄ nanomaterials for adsorbing Cr（VI）in wastewater. The sample containing 3% Ag achieved a Cr（VI）removal as high as 96.99% within 240 min, indicative of the most outstanding removal effect. With the increase of the dosage of functional nanomaterials, the adsorption effect was enhanced. The adsorption effect of the sample containing 3% Ag reached the maximum value of 99.24% at pH of 1, and theremoval of Cr（VI）could still maintain over 85% after 5 cycles, indicative of excellent cycling stability.
