Among the synthesized nanocomposites, the metal-organic nanocomposite (NiFe₂O₄@SiO₂@ HKUST-1) with 30% wt% showed better color removal. As a result, the kinetics for this nanocomposite metal-organic framework was calculated at different concentrations of a solution. All the above models were studied to find the kinetics of these nanocomposites (Fig 21).
