Patent

CA 2546477

Disclosed is a low-cost, environmentally friendly anion-adsorbing carbon material which is excellent in anion absorption. Also disclosed are a method and apparatus for producing such an anion-adsorbing carbon material. The present invention is characterized in that a raw material of plant origin is carbonized after being brought into contact with a solution containing calcium ions and then the resulting is brought into contact with an acid solution.

L'invention concerne une matière carbonée adsorbant les anions, peu coûteuse et sans danger pour l'environnement, et qui présente d'excellentes propriétés d'absorption d'anions. L'invention concerne aussi un procédé et un dispositif de production de cette matière carbonée. Le procédé est caractérisé par les étapes consistant à : carboniser une matière première d'origine végétale après l'avoir mise en contact avec une solution contenant des ions calcium, et mettre ensuite le produit obtenu en contact avec une solution acide.
