Abstract
A method of disinfecting a contact lens is disclosed and comprises placing the contact lens to be disinfected into a liquid electrolyte containing chlorine dioxide precursor, e.g., stabilized chlorine dioxide, and forming a disinfecting amount of chlorine dioxide in the liquid electrolyte by passing an electric current through the liquid electrolyte.
Claims19
A method of disinfecting an object comprising:
- placing an object into a liquid electrolyte containing chlorine dioxide precursor;
- and
- forming a disinfecting amount of chlorine dioxide in said liquid electrolyte containing said object by passing an electric current through said liquid electrolyte.
A method of producing a disinfectant comprising:
- providing an aqueous-based liquid electrolyte containing chlorine dioxide precursor;
- and
- forming chlorine dioxide in said aqueous-based liquid electrolyte in the presence of an object to be disinfected in an amount effective to disinfect said object to be disinfected by passing for a period of time an electric current through said aqueous-based liquid electrolyte.
A method of producing a disinfectant comprising:
- providing an aqueous-based liquid electrolyte containing a buffer component and chlorine dioxide precursor selected from the group consisting of stabilized chlorine dioxide, chlorite components and mixtures thereof, said chlorine dioxide precursor being present in an amount in the range of about 50 ppm to about 1000 by weight, calculated as potential chlorine dioxide;
- and
- passing an electric current through said aqueous-based liquid electrolyte in the presence of an object to be disinfected at conditions and for a period of time effective to form chlorine dioxide in said aqueous-based liquid electrolyte in an amount sufficient to effectively disinfect said object to be disinfected.
