The aim of this work is the study of Congo Red removal from water by adsorption onto Zn4Al-CO3 type layered double hydroxide prepared from zinc ash. The preparation consist in dissolution of zinc ash with hydrochloric acid followed by synthesis of LDH by co-precipitation of zinc chloride with aluminum salt in alkaline media. The prepared LDH and the calcined product were utilized as adsorbents of azo dye Congo Red from water. Despite that the materials were prepared from a waste, their performances as adsorbents are comparative with other similar materials prepared from analytical grade reagents. The structural analysis of the materials after Congo Red uptake reveals that the adsorption process appeared to be surface adsorption.
