An apparatus for extracting oxygen from an environment surrounding the apparatus, which comprises a container having an interior space isolated from physical contact with the environment at least in part by a gas permeable membrane having a first and a second side, wherein the membrane contacts the environment on the first side of the membrane, a carrier fluid in contact with the second side of the membrane in the first container, and a non-proteinaceous oxygen binding compound contained in the carrier fluid, wherein the compound comprises a tetradentate chelating molecule, a metal ion chelated in the molecule, and a nitrogenous base chelated to the metal ion, is disclosed along with a method for extracting oxygen from environmental fluids.

An apparatus for extracting oxygen from an environment in contact with said apparatus, which comprises: a container having an inlet, an outlet, and an oxygen permeable membrane which together at least in part define an inner space of said container, said membrane having a first surface adapted to be in contact with said environment and a second surface facing said interior space; a carrier fluid in contact with said second surface of said membrane in said container; and a non-proteinaceous oxygen binding compound contained in said carrier fluid, wherein said compound comprises a tetradentate chelating molecule, a metal ion chelated in said molecule, and a nitrogenous base chelated to said metal ion. A method for removing oxygen from a fluid environment, which comprises: contacting said environment with a first surface of an oxygen permeable membrane having a first and a second surface which separates said environment from an interior space of a closed container, and contacting said second surface of said membrane with a carrier fluid containing a non-proteinaceous oxygen binding compound which comprises a tetradentate molecule, a metal ion chelated by said molecule, and a nitrogenous base chelated to said metal ion, wherein said compound is not saturated with oxygen, thereby removing oxygen from said fluid environment and increasing oxygen concentration in said container.
