摘要:
To provide a method for obtaining an oxygen absorber which is capable of stably maintaining the oxygen absorption performance, while being suppressed in excessive heat generation in the atmosphere. A method for producing an oxygen absorber, wherein: an alloy (X), which contains (A) at least one transition metal that is selected from the group consisting of manganese group metals, iron group metals, platinum group metals and copper group metals and (B) at least one metal that is selected from the group consisting of aluminum, zinc, tin, lead, magnesium and silicon, is subjected to a treatment by an aqueous solution of an acid or an alkali, so that at least some of the component (B) is removed by dissolution; and an alloy (Y), which is obtained by removing at least some of the component (B), is treated with an aqueous solution of an inorganic acid salt or organic acid salt that is capable of forming a salt with the transition metal of the component (A), so that a metal salt is formed on at least a part of the surface of the alloy (Y).本發明係提供一種可得於大氣環境氣氛下抑制過度的發熱、而能維持安定之氧吸收性能之氧吸收劑的方法。本發明係製造氧吸收劑之方法,其包含將合金(X)提供至酸或鹼之水溶液處理而溶析去除合金(X)中所包含之成分(B)之至少一部分,且以無機酸鹽或有機酸鹽之水溶液處理前述成分(B)之至少一部分被去除之合金(Y),而於前述合金(Y)之表面之至少一部分形成金屬鹽而成;前述合金(X)包含(A)選自由錳族、鐵族、鉑族及銅族所成群之至少一種過渡金屬,與(B)選自由鋁、鋅、錫、鉛、鎂及矽所成群之至少一種金屬;前述無機酸鹽或有機酸鹽之水溶液為能與前述成分(A)之過渡金屬形成鹽者。
