Abstract:
An apparatus for binding oxygen on a surface of a carbon containing fiber comprising:(a) an annular light source inside a vertically oriented cylindrical container for irradiating the fiber as the fiber move vertically through the inside of the annular light source and, wherein the light source irradiates the fiber at a high intensity between about 1 and 40 watts/cm2 at wavelengths ranging from about 160 to 500 nanometers without higher wavelengths; (b) supply means for providing flowing ozone in the container which directs flow of the ozone from a lower portion of the container upwards on the surface of the fiber inside of the container during the irradiating by the light source; and (c) an electrical power supply operably coupled to power the optical energy source wherein the fiber after irradiating contains bound oxygen from the ozone.
