Abstract:
A method for the destructive sorption or destructive chemisorption of a target component, comprising:providing a quantity of finely divided adsorbent selected from the group consisting of MgO, CaO, TiO.sub.2, ZrO.sub.2, FeO, V.sub.2 O.sub.5, V.sub.2 O.sub.3, Mn.sub.2 O.sub.3, Fe.sub.2 O.sub.3, NiO, CuO, Al.sub.2 O.sub.3, ZnO and mixtures thereof wherein the finely divided adsorbent contains either reactive atoms selected from the group consisting of halogens and alkali metals stabilized on the surfaces of the adsorbent in an amount of at least two atoms of reactive atoms per square nanometer of adsorbent surface area or ozone, said adsorbent having an average particle diameter of from about 3 to 20 nanometers;contacting said adsorbent with a target component selected from the group consisting of hydrocarbons, halogenated hydrocarbons, bacteria, fungi and viruses;said contacting being carried out at a temperature of from about -40.degree. C. to 600.degree. C. and said contacting step causing the destructive sorption or destructive chemisorption of said target compound.
