RESUMO

A low-cost plasma hand sanitizer with minimum capital and running costs, combining flexibility in operation and high efficacy in treating common pathogens, is proposed for sanitizing the hands of medical doctors and nurses. Hands are exposed to a mist that is generated using tap water and activated by plasma coaxial dielectric barrier discharge (DBD) in ambient air. A common ignition transformer operating in the kilohertz range is used for the power supply, and a commercial ultrasonic nebulizer generates the mist. To enhance complete hand sanitization and reduce exposure time without adding oxygen gas to the discharge, solutions of commercial hydrogen peroxide in small concentrations are added to the water that is introduced in the plasma in the form of a mist. The active species produced by DBD during operation as O3 and OH is measured in the treatment zone near the end of the discharge tube. By adding increasing amounts of hydrogen peroxide in the water, we find that OH radicals increase, and measured ozone concentrations in ambient air decrease. This can be considered a beneficial chemical transformation, reducing possible harmful effects of ozone and enhancing sanitization efficacy. Sanitizing effects are reached with a low hydrogen peroxide concentration of 3 mg/L to avoid any harmful effects on the skin of the hands.
