A preparation method of an antibacterial deodorizing modified fiber for water purification is provided. Maleic anhydride is used to perform an addition reaction with sodium polysulfide to generate a disulfide antibacterial agent I, the disulfide antibacterial agent I continues to react with 2-amino-5-nitropyridine in an acetic acid solution under the catalysis of sodium acetate to obtain a compound II, then, the nitro in the compound II is reduced into amino by ferrous sulfate, meanwhile, anhydride is hydrolyzed into carboxylic acid in a faintly acid aqueous solution to obtain a compound III, and finally, under alkaline conditions, the amino in the compound III reacts with the cyan in a polyacrylonitrile fiber to obtain a modified polyacrylonitrile fiber. The prepared modified polyacrylonitrile fiber can remove various heavy metals in sewage and has good antibacterial and anti-mildew effects, thereby achieving the effects of water purification and deodorization.

Disclosed is a system and method of treatment which provides a direct response to the treatment of pneumonia as related to infections using a powder comprising a polyiodide resin with broad spectrum bactericidal, fungicidal and virucidal properties. When the powder is applied directly to the lungs of a mammal an immediate contact kill of protozoa, bacteria, fungi and viruses that cause respiratory tract infections affecting the lungs of a mammal takes place. Also disclosed is an application of the polyiodide resin powder for use with personal protective equipment (PPE) including but not limited to face masks, face shields, and respirators.

Also described herein are methods for making the copolymers described herein and their use in disinfecting compositions.

A method for treating foul odors. A chemical solution is administered to the area to be treated. The chemical solution includes: potassium iodine, zinc sulfate and magnesium sulfate. In a preferred embodiment the chemical solution is diluted in water and applied to an area needing treatment.

An aerosol-surface interface sanitization system comprising a non-toxic, non-corrosive and biocompatible sanitization formulation, and a nebulizer selected from jet-nebulizer, ultrasonic nebulizer or spray gun. This system is designed for interior environment application, and is applicable for both airborne and surface disinfection. The sanitization formulation is formed by membrane emulsification technique to optimize nebulization efficiency through adjustment in viscosity, droplet size, dispersion area and settlement rate, while having a high antiviral, antifungal and antibacterial activity.

A method of providing fragrance to a product releasable on exposure of the product to humidity, comprising (a) the encapsulation of fragrance in a particulate matrix by dispersing the fragrance in a solution of the matrix material and spray-drying the dispersion to give fragrance-containing particles; (b) dispersing the particles in an organic liquid non-solvent for the matrix material; and (c) adding the resulting particles to the product.

The particles thus treated do not separate so readily from the product, resulting in a longer-lasting fragrance.

Contact lens treatment systems and methods for disinfecting contact lenses are described. These systems and methods utilize a coated catalytic disc in combination with a fibrous catalyst. The coated catalytic disc contains a support disc and 6 to 300 mg of manganese present on at least a portion of the support disc, often in the form of manganese dioxide. The fibrous catalyst contains 25 to 50 mg iron, often in the form of an iron cation.
