Copper oxide nanoparticles were prepared by five sol-gel methods. The comparative study was made by the characterization such as FTIR, SEM- EDX, XRD. Out of these protocols, method five is more suitable and gives more accurate and appropriate results. From the data of EDX it is also found that method five gives higher yields of copper oxide nanoparticles. The efficiency of these nanoparticles as low cost adsorbent for the removal of methylene blue (MB) capacity from aqueous solutions was investigated. The effect of different parameters such as amount of adsorbent, concentration of dye, contact time, pH, temperature were studied the adsorption capacity and adsorption behavior of nanoparticles under various conditions. The experimental isotherm data has been studied. The kinetic study of the adsorption obeys Pseudo-first order model. The thermodynamic parameters namely Gibbs free energy, enthalpy, and entropy have revealed that the adsorption of methylene blue on the nanoparticles are feasible, spontaneous and exothermic.
Keywords: nanoparticals, sol-gel method, copper oxide, XRD.
