Abstract
Thermal decomposition of copper (II) acetate monohydrate and polyvinyl alcohol results in CuO/Cu2O nanocomposite synthesis. It was characterized by FT-IR, XRD, and TEM techniques. The peaks appeared in the FT-IR spectrum and the XRD pattern, confirming the CuO/Cu2O nanocomposite preparation. The TEM image shows that the particles are agglomerated. The CuO/Cu2O nanocomposite was used as a new adsorbent to remove methyl orange dye from the aqueous solution. The results of the dye removal study show that initial dye concentration has no effect on the removal percentage, and the dye removal percentage was constant at about 97%. However, dye removal increased with an increase in pH from 2 to 8, with the highest yield occurring at pH equal to 8. After increasing the pH and reaching 12, the removal percentage has been reduced. The dye removal efficiency increases to 99.5% by increasing the amount of adsorbent from 5 to 20 mg and by increasing the contact time from 5 to 30 minutes.
