摘要: An adsorbent for phosphoric acid-based anionic substances, that contains foamed glass, and that has a Ca2p concentration of 7.5 atom % or more or a Na1s concentration of 5.0 atom % or less at the surface thereof as measured by XPS analysis, and a half-width of Si2p peak of 2.4 eV or more. The adsorbent can also have a specific surface area of 45 m2/g or more or a pore volume of 2.5 cm3/g or more as measured by mercury intrusion.
