摘要：

We constructed a novel microwave-UV light sterilization system and investigated its sterilization effect. This sterilization system can emit UV light by irradiation of microwave without other power. When irradiating UV light with and/or without microwave on aqueous DMPO solution, active oxygen species such as hydroxyl radical or superoxide were generated in the solution. The amount of active oxygen species generated by irradiation of microwave and UV light was larger than that by irradiation of UV light alone. This would be due to the promotion of emission of UV light photons by microwave and UV light irradiation. Moreover, microwave-UV light sterilization was highly effective to sterilize microorganisms. The generation of active oxygen species would play an important role in sterilization of the sterilization system. (C) 2002 Elsevier Science B.V. All rights reserved.
