Process for manufacturing functional activated carbon fibers treated by anodic oxidation

摘要

The present invention relates to a process for manufacturing activated carbon fibers having greatly improved adsorption performance time and adsorption performance when in contact with surface oxides such as in the case where gas and liquid impurities are treated. The process of the present invention comprises the following steps:;a) placing conventional activated carbon fibers between an anode and a cathode plate in an acidic or an alkaline electrolytic solution, and;b) applying a certain voltage at a current density between said graphite anode and graphite cathode plate.;The present invention also relates to the product resulting from this process and the use of this product.
