Dialysis membrane
First Claim
1. A dialysis membrane formed of a high molecular weight film forming material as a continuous phase containing within the membrane an insoluble inorganic catalyst which does not wash out of the membrane and which converts hydrogen peroxide in dilute solution to water and oxygen during passage of the dilute solution of hydrogen peroxide thereinto from one side for release of oxygen from the opposite side in which the catalyst is selected from the group consisting of manganese dioxide, ruthenium oxide, ruthenium sulfide, colloidal silver, colloidal and chelated iron, platinum, silver and gold.

Abstract
A semi-permeable membrane containing a catalyst for conversion of hydrogen peroxide introduced from one side of the semi-permeable membrane to molecular oxygen which is released from the opposite side of the semi-permeable membrane. The catalyst is preferably in the form of a ruthenium oxide or sulfide and preferably in assymetrical distribution in the membrane.

- 4. A method of producing a dialysis membrane formed of a high molecular weight film forming material as a continuous phase containing within the membrane an insoluble catalyst in the form of a metal oxide or sulfide which converts hydrogen peroxide from dilute solution to water and molecular oxygen during diffusion of hydrogen peroxide from one side for release of oxygen from the opposite side comprising incorporating one of the components including a soluble salt of the metal and a soluble sulfide or hydroxide in the membrane and then wetting the membrane with a solution of the other component for reaction with the first component in situ in the membrane to precipitate the corresponding metal oxide or sulfide.
