The use of gaseous chlorine dioxide to sterilize surfaces, especially the gas impermeable surfaces of implements commonly employed in the medical sciences, such as those formed from porcelain, ceramics, metal, plastics and glass. The contaminated surfaces are contacted with an effective amount of gaseous chlorine dioxide for a time sufficient to kill bacterial spores at a temperature which does not overly exceed ambient temperature.

A method for sterilizing a substantially gas impermeable surface which is contaminated with spores comprises the steps of exposing the surface to a humid gaseous environment to enhance the susceptibility of the spores to subsequent chemosterilization, and then exposing the spores to an amount of gaseous chlorine dioxide in an inert carrier gas effective to sterilize the surface and a method for sterilizing an article contaminated with spores which comprises exposing the surface to a gaseous atmosphere comprised of chlorine dioxide gas and water vapor, wherein the amount of water vapor in said atmosphere is adapted to enhance the susceptibility of said spores to the sporicidal action of chlorine dioxide.

A method and apparatus for the generation, use, and disposal of chlorine dioxide is disclosed. A solid sodium chlorite composition having impurities, at least one of which is sodium hydroxide, is contacted with an agent to consume essentially all of the sodium hydroxide. Chlorine dioxide gas is then generated by contacting the resultant composition with chlorine in a humidified inert carrier gas. The resultant chlorine dioxide gas mixture may then be treated to remove chlorine gas present therein by contacting the same with soda-lime in particulate form. After using the chlorine dioxide gas mixture in the desired manner, chlorine dioxide present in the spent effluent gas may be substantially removed via the introduction of the effluent gas into an aqueous solution of sodium thiosulfate having a sufficient amount of an inorganic base to maintain the alkalinity of the solution during consumption of thiosulfate by chlorine dioxide.
