Several kinds of activated carbon fiber(ACF), or granular activated carbon (AC) loaded metallic silver particle or silver halides have been prepared by soaking ACF or AC in silver salt solution. The structure of the fibers was analysed by scanning electron microscopy (SEM) and powder X ray diffraction(XRD). The Ag content in the fiber was measured by an Inductively Coupled Plasma(ICP) emission spectroscopy. Antibacterial test was carried out against Escherichia coli(E. coli) and Staphylococcur aureus (S. a...
