Abstract: The bactericidal and virucidal efficacy of ultrasonic fogging with pH-controlled sodium hypochlorite (NaOCl) solutions was studied against Escherichia coli and influenza virus (Flu V) on solid surfaces in a confined space. The NaOCl solutions of pH 6 and 10 containing free available chlorine (FAC) of 2 to 1,000 mg/L were fogged at a rate of 2-3 mL/min, and fine fogged droplets (avr. 4 μm) were discharged by filtrated-compressed air at a rate of 0.01-0.05 m 3 /min. When the NaOCl solution of pH 10 was fogged, r…
