Abstract
Nanoparticles of CuO have been synthesized using precipitation method for methylene blue adsorbents. Copper chloride was used as precursor. Powder of copper chloride was dissolved in water and then precipitated using NaOH. The precipitate was dried and after that it was calcined at 300-500oC for 2 hours. The CuO nanoparticles was analyzed using X-ray diffraction (XRD). The specific surface area of the nanoparticles was measured using a surface area meter. The adsorbance of the CuO nanoparticles was tested by utilizing methylene blue as an example of dye waste. According to XRD data, all CuO nanoparticles calcined at 300-500oC were monoclinic with crystallite size 17-32.8 nm. The specific surface areas of the CuO nanoparticles were 26, 36, and 77.6 m2/g for calcination temperature of 500, 400, and 300oC that correspond to the particle size of 36.5, 26.4, and 12.2 nm. The best adsorbent for methylene blue was the CuO nanoparticles calcined at 400oC for 2 hours with an adsorption capacity of 61 mg/g at pH 7.
