METHOD FOR PRODUCING HIGHLY FUNCTIONAL ACTIVE CARBON FIBER HAVING ION EXCHANGE CHARACTERISTIC

Title:

METHOD FOR PRODUCING HIGHLY FUNCTIONAL ACTIVE CARBON FIBER HAVING ION EXCHANGE CHARACTERISTIC

Document Type and Number:

Japanese Patent JP3500399

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To obtain an active carbon fiber having a surface structure in which the polarity is highly developed and excellent adsorption performances.
SOLUTION: The active carbon fiber is subjected to an electrochemical surface treatment in an acidic or an alkaline, etc., electrolytic solution, preferably in the electrolytic solution of phosphoric acid (H3PO4) or potassium carbonate (K2CO3) to introduce functional groups into the surface of the carbon substrate.
