Étude comparative de l'élimination des ions Cu(II) en milieu aqueux par adsorption sur des argiles HDLs

Abstract

Les argiles anioniques de type hydroxydes doubles lamellaires (notés HDLs), faciles à synthétiser, non toxiques et peu coûteux, font partie des matériaux susceptibles d’apporter une solution dans le traitement des effluents en les utilisant comme adsorbants. Ces matériaux, naturels ou synthétiques ont été largement étudiés ces dernières années, en raison de leurs propriétés électrochimiques et d’échange anionique liées principalement à leur structure lamellaire. Dans la littérature, les procédés d'adsorption sur des HDLs montrent une efficacité et une performance importantes pour l’élimination des polluants. Ce travail porte sur une étude comparative d’adsorption du Cu(II) sur trois phases HDLs. Les phases étudiées dans ce travail, Mg2Al-CO3, Mg2[FeAl]-CO3 et Zn2[FeAl]-CO3, ont été synthétisés par la méthode de coprécipitation à pH constant. La caractérisation des HDLs a été effectuée par différentes techniques de caractérisation (DRX, MEB-EDX et BET). L’étude d’adsorption des ions Cu(II) sur les différents HDLs a été effectuée en mode statique pour une concentration initiale de l’ordre de 100mg/L en ions Cu2+.
