It is determined that indoor condensation of hydrogen peroxide vapor is to occur, if there is a solution with which both (Equation 1): PT €¢ y1 = P01 €¢ x1 €¢ ³1 and (Equation 2): PT €¢ y2 = P02 €¢ x2 €¢ ³2, which indicate vapor-liquid equilibrium, hold. With this, it is possible to accurately determine whether indoor condensation of hydrogen peroxide vapor is to occur or not in decontamination.
