Impact of Cu Ions removal onto MgO nanostructures - adsorption capacity and mechanism



This research aims to treat wastewater that has been contaminated with one of the most prevalent toxic heavy metals, Cu2+. The thermal pyrolysis process was used to manufacture MgO nanoparticles. Spectroscopy, X-ray diffraction (XRD). The production of MgO nanoparticles was validated using X-ray photoelectron spectroscopy (XPS) and energy-dispersive X-ray spectroscopy (EDX). 

Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) tests revealed spherical particles at the nanoscale (50 nm), with a BET surface area of 67 m2. g−1. The Cu2+ adsorption process was fast and well represented by the pseudo-second-order kinetic and Langmuir models. With a regression coefficient of 0.9960, the Langmuir pattern achieved the highest adsorption capability of Cu2+: 546.45 mg/g. The MgO nanoparticles generated for Cu2+ uptake are promising and could be used to eradicate other poisonous heavy metals in the aquatic media.
