A METHOD FOR DISINFECTING AND STERILIZING MICROBIAL CONTAMINATED MATERIALS

摘要

The method for disinfecting and sterilizing microbial contaminated or infectious materials, e.g. medical instruments, waste from medical laboratories or hospitals, comprises the following steps: (a) loading the material for disinfecting and sterilizing into a vacuum-proof sterilization chamber; (b) introducing liquid hydrogen peroxide into the sterilization chamber so as to penetrate the material; (c) introducing liquid acetic acid into the sterilization chamber so as to penetrate the material; (d) evacuating gas from the sterilization chamber so as to evaporate the liquid at least partially; (e) introducing gaseous ozone into the sterilization chamber; (f) treating the material in a sterilization chamber for a sufficient time period so as to disinfect and sterilize the materials. The germicide potency of the method is markedly improved in comparison with the method where only compound O3 is used alone or in combination with the germicide H2O2.
