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.
一种降低大气或液体中分子氧浓度的方法,所述方法包括以下步骤: 1:
(i) 用一定强度或波长的辐照、伽马射线照射、电晕放电、电子束照射或加热处理包含至少一种可还原有机化合物的组合物,以便将可还原有机化合物还原成可被分子氧氧化的还原形式,其中所述可还原有机化合物不是亚甲基蓝;以及
(ii) 将大气或液体暴露于所述组合物;
使存在于大气或液体中的至少一部分分子氧通过还原型可还原有机化合物的氧化作用被除去,以及
其中,所述步骤 (i) 和 (ii) 可按任一顺序进行,所述方法的特征在于,可还原有机化合物还原形式的氧化与过渡金属催化剂的存在无关。
