Ecofriendly Green Synthesis of Copper (II) Oxide Nanoparticles Using Corchorus olitorus Leaves (Molokhaia) Extract and Their Application for the Environmental Remediation of Direct Violet Dye via Advanced Oxidation Process

Abstract

In this research, copper (II) oxide nanoparticles were prepared by an ecofriendly green method using the extract of corchorus olitorus leaves (Molokhaia) as a surfactant, capping and anti-agglomeration agent. The ecofriendly green CuO NPs were characterized using different chemical and physical techniques and the results confirmed the formation of monoclinic tenorite CuO nanoparticles with an average particle size of 12 nm and BET surface area of 11.1 m2/g. The eco-friendly green CuO NPs were used in environmental remediation for the efficient catalytic degradation of direct violet dye via advanced oxidation process (AOP) in presence of H2O2. The impact of AOP environmental parameters affecting the degradation process was investigated. Moreover, the catalytic degradation of the direct violet dye using the ecofriendly green CuO NPs was studied kinetically and thermodynamically and the results showed that the catalytic degradation process agreed well with the pseudo-second-order kinetic model and the process was spontaneous and endothermic in nature. Finally, high catalytic degradation of the direct violet dye was observed when the eco-friendly prepared green CuO NPs were placed in real water samples.

Combination of ozone-based advanced oxidation process and nanobubbles generation toward textile wastewater recovery

“…Several approaches have been introduced within the past 2 decades focusing on the treatment of organics-contaminated wastewater, and the common method in the current applications is chemical oxidation (Asghar et al, 2015;Sun et al, 2015). Among other chemical oxidation processes, AOP is categorized to be a versatile approach in wastewater technology due to the in situ formation of reactive oxygen species (ROS) such as hydroxyl radicals (OH•) (Yan et al, 2022;Yasasve et al, 2022;Aljedaani et al, 2023).…”

Efficacy of copper oxide nanoparticles using Piper longum and Piper betle

“…P. Betle and P. Longum Longum (Long Pepper) are small perennial creepers, belonging to the family Piperaceae. Piperaceae crops are widely farmed in India, Sri Lanka, Malaysia, Thailand, Taiwan, and other Southeast Asian nations [ 14 , 15 ]. The primary components of these shrubs include volatile oil, carbohydrates, proteins, alkaloids, saponins, tannins, and mineral minerals (K, Mg, Na, Zn, Mn, and Co) necessary for human health, metabolic processes, healthy development, and lipid metabolism [ 16 ].…”
