Kind Code:
B2
Abstract:
A method of reducing the concentration of molecular oxygen present in an atmosphere or liquid, said method comprising the steps of: (i) treating a composition comprising at least one reducible organic compound with irradiation of a certain intensity or wavelength, gamma-irradiation, corona discharge, exposure to an electron beam or application of,heat, so as to reduce the reducible organic compound to a reduced form oxidisable by molecular oxygen, wherein said reducible organic compound is not methylene blue; and (ii) exposing the atmosphere or liquid to said composition; such that at least a portion of the molecular oxygen present in the atmosphere or liquid is removed through oxidation of the reduced form of the reducible organic compound, and wherein said steps (i) and (ii) are carried out in either order and said method is characterised in that the oxidation of the reduced form of the reducible organic compound occurs independently of the presence of a transition metal catalyst.
