Synthesis, description of nickle oxide nanoparticles and modifying its surface from waste batteries for efficient methyl orange dye removal: kinetic, isotherms and thermodynamic studies
Key Points
Methyl orange dye removal efficiency reached 98% using nickel oxide nanoparticles derived from waste batteries.
Kinetic studies showed that the adsorption process was rapid, achieving equilibrium within 60 minutes.
Isotherm models indicated that the adsorption fits best with the Langmuir model, suggesting monolayer coverage.
The thermodynamic studies revealed that the adsorption process is spontaneous and endothermic, implying favorable conditions.
