The synthesized of layered double hydroxide Zn-Cr and layered double hydroxide Zn-Cr/Cellulose composite by coprecipitation method were characterized by XRD, FT-IR and SEM-EDS analysis. The synthesized material was used as an adsorbent in the regeneration process and adsorption of malachite green dye with variations in pH, time, concentration and temperature. The regeneration of the adsorbent w…
