Fast oxygen absorber

  1. Jun 8, 2005 #1
    I am working on a project of a medical equipment which is supposed to absorb oxygen at a rate similar to the human body. I am looking for a process or a substance that would absorb about 200-300 ml of oxygen per minute. I can't use fire or anything that explodes. I was thinking about iron powder, but I don't think the oxydation reaction would have the correct rate. Does anyone know if iron is OK? Any other suggestions?

    Thanks,

    Tiago

    Have you looked into standar bulk getters like barium or titanium ? By fixing the mass of the getter and its temperature, you can tune the gettering rate.

    Thanks a lot for the help. I really think bulk getters are what I need, though I'm not familiar with the term. I've googled "bulk getters", but I didn't find a lot of information that could help me. Do you know any websites or books with information about bulk getters or where to buy them?
