Electroporation effect of ZnO nanoarrays under low voltage for water disinfection

Abstract It is quite necessary to develop a safe and efficient technique for disinfection of drinking water avoid waterborne pathogens infectious diseases. Herein, ZnO nanoarray electrodes with different sizes were investigated low-voltage high-efficiency electroporation disinfection. The results indicated that the nano-pyramid small tip width proper length exhibited over 99.9% efficiency against Escherichia coli under 1 V flow rate 10 mL/min (contact time 1.2 s). suitable size was optimized by establishing correlation between four kinds nanoarrays their disinfection, which can guide preparation next-generation electroporation-disinfecting electrodes.
