摘要

In this paper,the electro-analysis and spectrophotometric analysis methods were used to study the antibacterial ability of copper and stainless steel materials.When Escherichia coli (E.coli) and photo-bacteria were used as samples,the antibacterial effect of stainless steel was very weak,while the percentage of bacteria dying from exposure to metallic copper for 30 min was over 90%.The antibacterial ability of copper has a potential application in the field of disinfection,food packaging and piping of drinking water.
