摘要/Abstract

摘要： An Ag-MnFe₂O₄-bentonite composite was synthesized by a chemical co-precipitation method and used for adsorption removal of Pb(Ⅱ), Cd(Ⅱ) and disinfection. The result of X-ray diffraction indicate that the diffraction peaks of MnFe₂O₄ and Ag can be perfectly indexed to the cubic spinel MnFe₂O₄(JCPDS No.88-1965) and metallic Ag(JCPDS No.41-1402), respectively. The results of scanning electron microscopy and energy dispersive X-ray spectroscopy manifest the deposition of MnFe₂O₄ and Ag on the bentonite surface and the presence of Mn, Fe and Ag. The result of X-ray photoelectron spectroscopy displayed that the composition of Ag-MnFe₂O₄-bentonite was Mn(Ⅱ), Fe(ⅡI) and metallic Ag. The analysis of Brunauer-Emmett-Teller showed that the specific surface area of Ag-MnFe₂O₄-bentonite was the largest compared with that of bentonite, MnFe₂O₄ and MnFe₂O₄-bentonite. Thermodynamic studies revealed that the adsorption of Pb(Ⅱ) and Cd(Ⅱ) ions was spontaneous and endothermic. Langmuir model showed an adsorption capacity of 129.87 mg/g for Pb(Ⅱ) and 48.31 mg/g for Cd(Ⅱ) ions. The adsorption kinetics of Pb(Ⅱ) and Cd(Ⅱ) ions onto Ag-MnFe₂O₄-bentonite can be best described by a pseudo-second-order model. The adsorption rate constant of the pseudo-second-order model was 0.0019 g·mg^-1·min^-1 for Pb(Ⅱ) and 0.0065 g·mg^-1·min^-1 for Cd(Ⅱ) ions. In addition to the adsorption experiment, the antibacterial properties of Ag-MnFe₂O₄-bentonite were studied through plate count method. Gram-negative(G-) bacteria Escherichia coli and Gram-positive(G+) bacteria Lactobacillus plantarum were used to test the antibacterial properties. The results showed that the composite demonstrated excellent antibacterial activity. Thus, Ag-MnFe₂O₄-bentonite can be employed as an adsorbent as well as an antimicrobial agent.
