Provided is an iodine-supporting composite material, which controls the volatility and elution of iodine by making iodine supported on plural kinds of activated carbon or fiber and mixing them, thereby the intensity of the bactericidal effect against microorganism can be changed. Migrating iodine from the state strongly retained in a material such as activated carbon or fibers to the material such as activated carbon or fibers having weak iodine adsorptivity which is made contacted, mixed, compounded, or mixed-spun with the strong iodine-adsorptivity materials, thereby, the rate of releasing iodine into the air or elution in water can be controlled. The iodine acts on the surrounding microorganisms in proportion to the rate at which iodine volatilizes or elutes and the intensity of these actions can be controlled.

The invention is concerned with a pharmaceutical and industrial iodophor preparation, its synthesis and potential applications. The compound has predictable antimicrobial activities. Furthermore, this iodophor is much more stable in the presence of organic material than traditional iodophors. The compositions release free iodine when in solution, which provides the antimicrobial activity.

This disclosure provides a method of disinfecting a surface within an area, comprising the steps of: a) dispersing into the area a multiplicity of droplets of a first aqueous composition comprising a first iodine reactant compound that is either a peroxide compound or an iodine salt compound: b) allowing sufficient time for the first aqueous composition to distribute throughout the area, and to deposit and coalesce into a layer upon the surface: c) dispersing into the area a multiplicity of droplets of a second aqueous composition comprising a second iodine reactant compound that is the other of the first iodine reactant compound, and: d) again allowing sufficient time for the droplets of the second aqueous composition to deposit onto the coalesced layer of the first aqueous composition, thereby forming iodine and other iodine biocides in situ and disinfecting the surface.
