Antibacterial Activity of Zinc-ContainingActivated Carbon Fibers

摘要

In this article several kinds of activated carbon fibers, using sisal fiber as precursors, were prepared with steamactivation or with ZnClZnCl2 activation. Zinc or its compounds were dispersed in them. The antibacterial activity of theseactivated carbon fibers were determined and compared. The research results showed that these sisal based activated carbonfibers supporting zinc have stronger antibacterial activity against Escherichia coli and S. aureus. The antibacterial activity isrelated to the precursors, the pyrolysis temperature, and the zinc content. In addition, small quantity of silver supported onzinc-containing ACF will greatly enhance the antibacterial activity of ACFs.
