Synthesis and Application of Two-dimensional Layered Double Hydroxides Nanocomposite Functionalized with Titanium Dioxide (LDH@TiO2) in the Removal of Orange Acid Dye from Aqueous Solutions: Thermodynamic, Isotherm and Kinetics Studies
Key Points
Effective removal of orange acid dye was observed using the LDH@TiO2 nanocomposite, indicating high efficiency.
Kinetic studies revealed that dye adsorption fits well with the pseudo-second-order model, showcasing rapid removal kinetics.
Thermodynamic analysis showed that the dye removal process is spontaneous with positive changes in entropy, supporting feasibility.
Isotherm models indicated that the adsorption capacity increases with higher dye concentrations, guiding optimization efforts.
