چکیده
In the present study copper oxide nanoparticles (CuNPs) were synthesized via simple and eco-friendly green route using black tea extract . Characterization of (NPs) was undertaken. The characteristic absorption peak CuNPs in range (352-355) nm UV–Vis spectrum. Scanning electron microscopy (SEM) transmission (TEM) studies revealed morphological structural character NPs. particle size 25-50 nm. Energy dispersive spectroscopy (EDX) showed high intense metallic (Cu), oxygen (O), carbon (C) low peaks phosphorus (P) , calcium (Ca) sulfur (S), potassium (K) elements due to capping action biomolecules plant formation. X-ray diffraction (XRD) pattern distinctive corresponding (200), (220) (311) planes revealing crystalline nature dyeing behavior treated fabric with Acid Black 172 (AB 172) has been studied build up dye, measured as exhaustion percentage (E%). Dye adsorption rate constants according pseudo-first order, pseudo-second intra-particle diffusion kinetic models calculated. Moreover, dye equilibrium data fitted well Freundlich isotherm rather than Langmuir isotherm. overall process follow order kinetics, Intraparticle Elovich model. treatment produces a nylon advanced color fastness antibacterial properties enabling them improve human health care reducing temperature, environmental impacts, damage, amount dyestuff used saving energy conventional fabrics. This review focuses on synthesis environmentally benign reagents minimal time paves way for future toxicity without risking interference from potentially toxic agents. use this technique treat may lead new coloration other functional improvement.
