PURPOSE:To provide a process for producing a modified pitch-based carbonaceous fiber capable of effectively adsorbing and removing trihalomethane precursor substances. CONSTITUTION:The modified carbonaceous fiber can be produced by hydrophilizing a carbonaceous fiber having a specific surface area of 0.1-1,200m<2>/g with an oxidizing agent, supporting an alkaline earth metal on the hydrophilized surface and activating the product. |
