Abstract
Disclosed herein are activated carbons having high decolorization performance in liquid phases, especially in liquid phases having relatively high viscosities, such as sugar liquids, and methods for producing the activated carbons. Activated carbons disclosed herein include activated carbons having a pore volume at a pore diameter of 10 to 10000 nm measured by the mercury intrusion method of 0.8 to 1.9 mL/g, and having a pore volume at a pore diameter of 300 to 1000 nm measured by the mercury intrusion method of 0.19 mL/g or more.
