Abstract
The Ag-treated activated carbon was prepared by the impregnation of Ag on the home made activated carbon. We investigated the nitrogen adsorption property, surface structure, and antibacterial activity of the carbon. The BET surface areas of Ag impregnated activated carbon are distributed to <TEX>$740-1112.2m^2/g$</TEX> region. The results of nitrogen adsorption property show that BET surface areas move gradually to lower value with increasing <TEX>$AgNO_3$</TEX> mole concentration. From the SEM results, we observed window blocking effect for micropores of external surface of adsorbent by Ag impregnation. Escherichia coli which is a kind of colon bacillus was used as bacteria for antibacterial test. From these results, we also observed that activity increase gradually to larger range with increasing <TEX>$AgNO_3$</TEX> mole ratio.
