Method for producing highly functional activated carbon fiber having ion exchange properties

摘要

PURPOSE: An active carbon fabrics is provided, which has excellent adsorption selectivity to little pollution source as well as recovery and removal of various heavy metal ion in liquid phase. CONSTITUTION: Acid or base solution is used as electrolytic solution, especially H3PO4 and K2CO3 is more preferable. Concentration of solution is 1-40wt.%. The carbon adsorbent is prepared by electro-chemical surface-treatment of active carbon fabrics with good adsorption property for 2-30 minutes with supplying 0.1-5.0 A current in acid or base solution.
