Removal of alizarin red-S from aqueous solution by adsorption on nanocrystalline Cu0.5Zn0.5Ce3O5

In this work, the nanocrystalline mixed oxide Cu0.5Zn0.5Ce3O5 synthesized by combustion method. The characteristic studies were performed by XRD, SEM and TEM analysis to investigate particle size of oxide. It was then used as an adsorbent for alizarin red-S from aqueous solutions. The alizarin adsorption capacity of the nanocrystalline oxide was studied with various factors such as temperature, pH of dye solution, initial dye concentration & contact time. The adsorption isotherms were agreed with the Langmuir & Freundlich isotherm models. Freundlich isotherm was well analogous with experimental results. According to the experimental results about 83% alizarin red-S was removed from aqueous solutions at lower temperature
