Disinfection method using disinfectant formed in situ by reaction of H2O2 with NO2 -

摘要

The present invention includes H2O2 and NO2 -, including a mixing step and partitioning step, with respect to an antiseptic method.The mixing step and the distribution step (the surface disinfected points are moistened by the solution of the active material) are performed at the treatment period ZA.The exposure steps follow them, and the distributed active solution acts over the exposure period Ze on the surface of the active solution contacting the active solution.In this method, the maximum NO2 - concentration at the mixing step is 300 mm, the time integral reaction rate W is represented by the integral equation (I) during the exposure period Ze, and K1 is the pH dependent rate constant of the reaction between H2O2 and NO2 -, and the pH may also be time-dependent The pH of the active solution prior to contacting the disinfecting surface is in the range of 2.1 ≦ pH < 6.8.The present invention relates to a device that provides an active material solution.
