Removal of heavy metals lead and copper ions from waste water using green synthesized MnO2/Mn2O3 nanoparticles
View through CrossRef
The current study examined the removal of lead and copper ions from aqueous solutions
using a variety of experimental techniques by producing manganese oxide sorbent
nanoparticles (MnO2/Mn2O3-NPs) from a sunflower seed husk extract (Helianthus
annuus). Key factors that affected the adsorption process were the pH level, contact time,
starting metal ion concentration, and dose of the nanoadsorbent. Numerousanalytical
methodswere employed to confirm the environmentally friendly manufacturing of
MnO2/Mn2O3-NPs.According to the data, the MnO2/Mn2O3 -NP had an average size of
roughly 26.93 nm.The adsorption reaction rate was analyzed by comparing pseudo-firstand pseudo-second-rate models.According to the recorded data, lead and copper ions
adsorption response on the MnO2/Mn2O3-NPs agreed on the paradigm of pseudo-second
order. Langmuir and Freundlich's models assessed lead and copper sorption onto the
absorbed substance.Considering the parameters that each model yields, the Langmuir
isotherms emerge as the favoured choice for the adsorption of Pb2+and Cu2+ions on
MnO2/Mn2O3 nanoparticles. MnO2/Mn2O3-NPs show promise as an adsorbent material to
remove heavy metals from water solutions.
