SYNTHESIS AND CHARACTERIZATION OF LAYER DOUBLE HYDROXIDES AND THEIR APPLICATION ON ADSORPTION OF BROMOPHENOL RED FROM AQUEOUS SOLUTION Author(s): Miloud AISSAT ,S. Hamouda, N. Bettahar, B. J. Abu Tarboush, A. Bahmani , N. Benhadria J. Ponte - Oct 2020 - Volume 76 - Issue 10 doi: 10.21506/j.ponte.2020.10.2 Abstract: Our contribution consists in using HDL as a means of sorption of dyes which are considered as polluting agents of waters especially for the industry textile. This study considers the removal of the Bromophenol red (BR) from water on calcined MgAl, ZnAL and MgZnAL-layered double hydroxides. The different LDH was prepared by copreprecipation method. The materials was obtained for molar ratios R =2 for the different LDH. The carbonated layered calcination of these solids leads to the formation of mixed oxides which have the property of being able to be regenerated by adsorbing new anionic entities. Adsorbents and adsorption products were characterized by physicochemical techniques. The structural characterization of the material was carried out by X-ray diffraction, infrared spectroscopy (FTIR). Dosages of the polluted solutions were monitored by UV-Visible spectrometry.
