Patent ID: 8048930

Claim:
An activated biocidal aqueous solution containing 0.1 to 20% (w/w) hydrogen peroxide obtained by subjecting a solution of 0.1 to 20% (w/w) hydrogen peroxide in demineralized, distilled or chemically pure water to a non-thermal electrical discharge process, wherein said biocidal solution has a pH in the range of 2 to 4, an oxidation-reduction potential (ORP) in the range of 400 to 600 mV, and the solution when having a peroxide content in the range of 0.1% to 5% (w/w) has a conductivity in the range of 100 to 450 μSiemens/cm, and the solution when having a peroxide content in the range of 5% to 20% (w/w) has a conductivity in the range of 100 to 350 μSiemens/cm.
