By subjecting such as corona discharge or glow discharge plasma, the non-thermal-discharge process, an aqueous solution of the initial hydrogen peroxide activated biocidal aqueous solution containing available, hydrogen peroxide present invention (activated I disclose the peroxide solution). Containing (w / w) from 0.05 to 20% hydrogen peroxide, activated peroxide solution results, and has a (ORP) pH in the range of 2 to 4, the redox potential in the range of 400~600mV , and has an electrical conductivity in the range of 100~500μ Siemens / cm, the solution when having a peroxide content in the range 0.05% to 0.5% (w / w) 0.1% to 5 % has an electrical conductivity in the range of 100~450μ Siemens / cm, and the solution when having a peroxide content in the range of (w / w) is in the range peroxide 5% to 20% (w / w) solution when having a content, has an electrical conductivity in the range of 100~350μ Siemens / cm. The pH, electric conductivity and ORP, the presence of the additional compound can be measured in the absence substantially in the solution. Biocidal activity of the solution is substantially higher than that of the peroxide solution in general. Biocidal solution may be used for any purpose where the preservative activity and bleaching activity and / or is required cleaning and disinfecting activity and / or activity and / or fungicidal activity and / or. In addition, for the preparation of the activated peroxide solution, non-thermal discharge treatment, the present invention discloses a pulse corona induced low frequency pulsed DC plasma discharge treatment in particular.
