Abstract

A process includes removing air bubbles from extracorporeal blood via chemical entrapment of nitrogen (N 2 ) gas.

Claims (5)

1. A process comprising removing air bubbles from extracorporeal blood via chemical entrapment of nitrogen (N 2 ) gas, wherein the chemical entrapment includes dinitrogen fixation by an organometallic complex.

2. The process of claim 1 , wherein the organometallic complex includes a titanium (IV) complex.

3. The process of claim 1 , wherein the organometallic complex is bound to a surface of an alumina particle.

4. The process of claim 3 , wherein the alumina particle includes nanoparticulate alumina.

5. The process of claim 4 , wherein the nanoparticulate alumina includes a powder having a surface area in a range between 60 m 2 /g and 70 m 2 /g.
