Résumé
L’élimination de la couleur de solutions aqueuses du rouge de chlorophénol a été étudiée par adsorption sur une hydrotalcite de synthèse calcinée. Le solide [Mg-Al-CO3] a été préparé par coprécipitation à pH constant et selon un rapport molaire Mg/Al = 2. Les études par diffraction des rayons X et spectroscopie infrarouge à transformée de Fourier (FTIR) ont montré que le matériau obtenu correspond aux composés de type hydrotalcite avec une bonne cristallinité. L’interaction de ce matériau avec le colorant montre que la cinétique d’adsorption est rapide et suit une expression de vitesse d’adsorption du second ordre. Les influences du pH, de la concentration de l’adsorbant, de la concentration en rouge de chlorophénol de la solution et d’ions compétiteurs tels que chlorure et carbonate ont été étudiées afin d’optimiser l’adsorption. Le traitement de solutions contenant de 0,015 à 1,5 mmol ∙L-1 de rouge de chlorophénol a donné des résultats prometteurs. La capacité d’adsorption de l’hydrotalcite calcinée est d’environ 1,7 mmol∙g-1. Les hydrotalcites calcinées pourraient constituer d’intéressants supports pour le piégeage du rouge de chlorophénol.

Abstract
The color removal from aqueous solutions of chlorophenol red by adsorption on a calcined synthetic hydrotalcite was investigated. The solid [Mg-Al-CO3] was prepared by coprecipitation at constant pH and with an Mg/Al molar ratio of 2. The studies by X-ray diffraction (XRD) and infrared spectroscopy FTIR (Fourier Transform InfraRed spectroscopy) have shown that the material obtained corresponds to the hydrotalcite-like compounds with good crystallinity. The interaction dye-hydrotalcite shows that the kinetic of adsorption is fast and follows the second order model. The effects of the pH, adsorbent concentration, chlorophenol red concentration and competitive ions such as chloride and carbonate on the adsorption were studied. Solutions containing from 0.015 to 1.5 mmol∙L-1 of chlorophenol red were successfully treated. The adsorption capacity of the calcined hydrotalcite is close to 1.7 mmol∙g-1. This suggests that the calcined hydrotalcites could constitute interesting supports for the trapping of chlorophenol red.
