Separation of Oxygen from Liquid or Vapor
Oxygen and its compounds constitute about half of the Earth's crust by weight. Oxygen can exist as part of a very wide variety of compounds or as a gas (O2). The compounds that oxygen forms can be accessed in this index by the other elements in the compound.

The simplest compound of oxygen is arguably hydrogen peroxide (H2O2). DuPont's ion exchange resins are frequently used to remove a variety of metals from H2O2 solutions. For more information on specific metals see the Periodic Table.
AmberSep Optipore™ Polymeric Adsorbents are used to remove organic compounds from H2O2. While hydrogen peroxide is not very ionic, it is a strong oxidizing agent. Since ion exchange resins are made from organic plastics they can be oxidized.
Caution: Oxidizing agents such as nitric acid attack organic ion exchange resins under certain conditions. This could lead to anything from slight resin degradation to a violent exothermic reaction (explosion). Before using strong oxidizing agents, consult sources knowledgeable in handling such materials.
Since O2 gas is often used in a compressed form, it may be contaminated with compressor lubricants.
AmberSep Optipore™ V493 Polymeric Adsorbent has been shown to work well to remove these compressor lubricants from compressed gas streams1 and AmberSep Optipore V503 Polymeric Adsorbent could also be tested for comparison.
