Eco-friendly and cost-effective the way its synthesis of copper oxide nanoparticles (CuO NPs) using Anchusa strigosa L. flower aqueous extract at lab. temperature was examined. The made CuO NPs were characterized by UV–VIS spectroscopy, FTIR. spectroscopy and X-ray diffraction techniques. The synthesized particles were very stable, globular in shape with an average diameter (28.22) nm. The CuO NPs were applied for their adsorption activity to remove the basic Safranine dye from aqueous solution. A series of experiments have been tested to show the effect of a variety of factors on depigmentation. Langmuir, Freundlich, Temkin and Halsey adsorption isotherm models are used to interpret the experimental results. The thermodynamic parameters "ΔS, ΔH, ΔG" were calculated and interpretation in the mean of the chemical function of the adsorbent. [ABSTRACT FROM AUTHOR] |
