Title (EN) METHOD FOR ADSORPTION OF TOXIC CONTAMINANTS FROM WATER
(FR) PROCÉDÉ D'ADSORPTION DE CONTAMINANTS TOXIQUES DANS L'EAU
Abstract:
(EN) The present disclosure provides an iron-modified montmorillonite adsorbent for effectively removing heavy metals from water. The iron modified montmorillonite can be synthesized using a facile intercalation wet synthesis procedure that requires low energy and minimal use of chemicals. The iron modified montmorillonite adsorbent effectively removes heavy metals, such as arsenite, strontium, barium, phosphate, from water.
(FR) La présente invention concerne un adsorbant à base de montmorillonite modifiée par du fer pour éliminer efficacement les métaux lourds de l'eau. La montmorillonite modifiée par du fer peut être synthétisée grâce à une procédure de synthèse humide par intercalation facile qui nécessite peu d'énergie et une utilisation minimale de produits chimiques. L'adsorbant à base de montmorillonite modifiée par du fer élimine efficacement les métaux lourds de l'eau, tels que les arsénites, le strontium, le baryum et le phosphate.
