Preparation of magnetic antibacterial composite beads Fe3O4/alginate/Ag
Keywords:magnetic antibacterial beads, sodium alginate, silver nanoparticles, water disinfection
In recent years, the synthesis of magnetic polymer beads has attractive much attention from many technological fields such as biomedical and environmental. In addition of stabilizing effect for magnetic particles core, the polymer shells can also be further functionalized, thus enlarging the spectrum of possible applications of magnetite nanoparticles. In this study, the novel magnetic composite beads Fe3O4/alginate/Ag were synthesized and characterized for point-of-use water disinfection. Magnetite nanoparticles were prepared from waste spent pickling liquors and then were encapsulated by natural alginate to form the spherical beads of the size about 1-2 mm. Silver nanoparticles were loaded on the beads with the large content (24.62 wt.%). The as-prepared beads have a high saturation magnetization value, Ms = 59 emu/g, and very good antibacterial activity against both gram (-) and gram (+) bacteria. With the concentration 35 μg mL-1 the magnetic beads can kill 100% Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa, whereas this value found 70 μg mL-1 for Lactobacillus fermentum, 105 μg mL-1 for Salmonella enterica, and 140 μg mL-1 for Bacillus subtilis.
