METHOD FOR STORING OXYGEN ABSORBING AGENT |
| 摘要 |
The method for storing an oxygen absorbing agent according to the present invention comprises: providing an oxygen absorbing agent comprising a metal, the metal having been obtained by subjecting an alloy comprising (A) at least one transition metal selected from the group consisting of iron, cobalt, nickel and copper and (B) aluminum to treatment with a basic aqueous solution to elute and remove at least a part of the aluminum (B), the oxygen absorbing agent having a specific surface area of at least 10 m2/g as measured by a BET method; and immersing the oxygen absorbing agent in an aqueous solution containing a chelating agent to store the oxygen absorbing agent. |
