Abstract
The take a look at highlights the potential of making use of agricultural by way of-merchandise for sustainable nanoparticle synthesis and their packages in environmental remediation. This paper offers a green synthesis method for (CeO2) nanoparticles the use of ethanol extract from Citrus aurantium peels sourced from Al-Hussainiyah, Iraq. The green synthesis method leverages the herbal antioxidant of Citrus aurantium peels, presenting a sustainable and green alternative. The synthesized CeO2 nanoparticles have been characterized the usage of numerous techniques, along with FTIR spectroscopy, XRD, FE-SEM with (EDX) and BET. The nanoparticles exhibited like-rose berry morphology with a mean crystal size of 12 nm and excessive crystallinity. BET analysis indicated a specific surface area of 173.309m²/g and a mean pore diameter is 3.06nm, ensuring a mesoporous structure. The perfect removal of 10 ppm of eosin yellow dye using 0.025 g of CeO2 NPs turned into pH 6 at 90 min which agreed with zeta potential analysis, and the adsorption process followed pseudo-second-order kinetics. The ΔHo of adsorption is 13.430 kJ/mol due to this reaction being physical adsorption. The reusability study showed the CeO2NP could be successfully used up to the 3rd cycle before a loss of 50% from efficiency.
