Ion-exchange resins with particle size of 0.5 mm were treated by an aqueous solution of MgSO_4 and then they were carbonized for 1 h in a nitrogen gas at the temperature ranging from 300 to 1000℃. The amount of MgO in carbon samples was about 30 mass%, irrespective of carbonization temperature. The antibacterial activity of carbon samples containing MgO was examined by the colony count method. The pH values in physiological saline dispersed with in carbon samples were in the range of 9.4-9.8, but the values did not affct the occurrence of antibacterial activity. From the antibacterial tests, it was found that the antibacterial activity for Escherichia coli and Staphylococcus aureus on carbon samples containing MgO increased with the increase of the carbonization temperature of the ion-exchanged resin.
