In the current work, CuO nanoparticles were deposited on natural zeolite’s particles to resolve the drawbacks of zeolite catalysis. The synthesized composites were characterized by XRD, SEM, BET, and DRS analyses. The results illustrated that in the 15% CuO composite, CuO nanoparticles with a size of 21 nm are deposited on the surface of the zeolite particles. Deposition of CuO nanoparticles on zeolite’s particles decreased the specific surface area from 35 m2/g (pure zeolite) to 28 m2/g (20% CuO composite), and causes a red shift in the absorption edge of the sample to 796 nm for 20% CuO composite. In order to compare the samples’ performances in eliminating water pollutants, methyl orange dye removal was investigated. The analyses indicated that the optimum efficiency (85% in 120 min) belongs to zeolite-15% CuO composite with a band gap of 1.70 eV.

Degradation Of Methyl Orange

Background: The study focuses on the synthesis of chitosan/ Fe2O3 nanocomposite, its characterization and application in methyl orange dye degradation. Methods: The synthesized chitosan/ Fe2O3 nanocomposite was characterized with Powder X-Ray Diffraction, Fourier Transformation Infrared Spectroscopy (FTIR), Transmission Electron Microscopy (TEM) and UV-Vis Spectroscopy. Results: The characterization showed that the Fe2O3nanoparticles were embedded in the polymer matrix of chitosan. The size of the Fe2O3nanoparticles were less than 10nm and the crystallite size was 1.22 nm.The synthesized chitosan/ Fe2O3nanocomposite was tested for methyl orange degradation using different parameters such as effect of contact time, effect of dose, effect of concentration and effect of pH for the degradation of methyl orange dye in aqueous solution.The Fruendlich, Langmuir and Temkin isotherm studies were also conducted for adsoption of methyl orange on Chitosan/ Fe2O3nanocomposite. Conclusion: The study indicated that the synthesized chitosan/Fe2O3 nanocomposite had the potential of degrading methyl orange dye up to 75.04% under the set condition in this experiment which indicate that Chitosan/ Fe2O3 nanocomposite is a viable option that can be used for the degradation of methyl orange dye.
