摘要

PROBLEM TO BE SOLVED: To provide a washing method of a porous carbon material for removing an alkali metal component cheaply and efficiently. SOLUTION: The washing method of a porous carbon material is a washing method of a porous carbon material containing alkali metal components, which is characterized by having a first washing step for washing the porous carbon material with a washing liquid which is obtained by supplying carbon dioxide gas into a washing liquid, and a second washing step for washing the washed porous carbon material with a washing liquid containing an organic acid.
