摘要:
The zero-valent transition bimetallic system has an excellent performance in antibacterial, but its worse stability, dispersibility and complex preparation process affect its application in water treatment. In this study, we synthesized a magnetic biochar-supported Fe-0/Cu-0 (BC@Fe-0/Cu-0) using waste reed straw, iron salts and copper salts as raw materials by a green and facile one-step carbothermal reduction for Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus) inactivation. Results indicated that the introduce of biochar not only improved the dispersion of metal particles, bu...
