Abstract
(EN)
Provided is a method for preparing an anion adsorbent, comprising the steps of: mixing two or more metal salts to prepare a stacking structure in which cationic compound layers and anionic compound layers comprising anions and water of crystallization are alternately stacked on one another; subjecting the stacking structure to primary heat treatment to expand a gap between the cationic compound layers, thereby preparing a preliminary anion adsorbent; and subjecting the preliminary anion adsorbent to secondary heat treatment to remove the anions and the water of crystallization of the anionic compound layers, except that at least one of the anions remains, thereby preparing an anion adsorbent.
(FR)
L'invention concerne un procédé de préparation d'un adsorbant d'anions, le procédé consistant : à mélanger au moins deux sels métalliques afin de préparer une structure empilable dans laquelle des couches de composé cationique et des couches de composé anionique comprenant des anions et de l'eau de cristallisation sont empilées en alternance les unes sur les autres ; à soumettre la structure empilable à un traitement thermique primaire afin d'élargir un vide entre les couches de composé cationique, ce qui permet de préparer un adsorbant d'anions préliminaire ; et à soumettre l'adsorbant d'anions préliminaire à un traitement thermique secondaire afin d'éliminer les anions et l'eau de cristallisation des couches de composé anionique, sauf qu'au moins l'un des anions reste, ce qui permet de préparer un adsorbant d'anions.
