Abstract
A medium for purifying fluids containing toxic compounds can be made by a method which comprises applying a dispersion of a halogenated heterocyclic N-halamine in an inert liquid carrier to the surface of a substrate having a high surface area and allowing the inert liquid carrier to penetrate into the substrate, wherein the inert liquid carried does not react with halogen atoms in the halogenated heterocyclic N-halamine, wherein the halogenated heterocyclic N-halamine is capable of destroying the toxic compound by oxidative action, and wherein the halogenated heterocyclic N-halamine becomes deposited on the surface of the substrate after the inert liquid carrier penetrates into the substrate.

A method for manufacturing a medium for purifying fluids containing toxic compounds which comprises applying a dispersion of a halogenated heterocyclic N-halamine in an inert liquid carrier to the surface of a substrate having a high surface area and allowing the inert liquid carrier to penetrate into the substrate, wherein the inert liquid carried does not react with halogen atoms in the halogenated heterocyclic N-halamine, wherein the halogenated heterocyclic N-halamine is capable of destroying the toxic compound by oxidative action, wherein the halogenated heterocyclic N-halamine in the inert liquid carrier is dispersed in the form of particles which are in the particle size range of about 0.01 μm to 20 μm, and wherein the halogenated heterocyclic N-halamine becomes deposited on the surface of the substrate after the inert liquid carrier penetrates into the substrate.
