Abstract

An Ag+ solution was made by supplying pure metal silver in filtrated distilled at constant voltage. the solution at an Ag+ concentration of 10 ppm showed specific activity against Gram positive and negative bacteria, and more than 90% activity against Candida albicans ATCC 102321 at the same concentration. The ionic solution produced was stable with regard to antibacterial activity and an Ag+ Concentration in the temperature range of 4$^{\circ}C$∼37$^{\circ}C$ for more than 4 weeks. In addition, the no pH change was observed under there conditions and the solution was confirmed stable by adjusting pH from 5.5 to 6.5.
