ZrO2/CeO2 nanocomposites were prepared using the co-precipitation (ZCP11, ZCP12 and ZCP21 samples) and
hybrid combustion-ultrasonication (ZC11, ZC12 and ZC21 samples) methods, following by the calcination. The
characterization of the synthesized ZrO2/CeO2 nanocomposites was achieved by utilizing several analytical
techniques such as High-resolution transmission electron microscopy, X-ray diffraction, Fourier transforms
infrared spectra, BET method and Field emission scanning electron microscopy. The optimum conditions were
evaluated from the batch method: pH = 3, 250 mg/L of AG1 dye, 0.05 g dose adsorbents, and equilibrium time
(90–200 min according to the sample). The adsorption isotherm, kinetic and mechanism models analyzed using
the extracted experimental data for the elimination of Acid Green 1 dye over ZCP11 and ZC11 samples. Besides,
the thermodynamic factors were investigated at 293–303 K. The optimum conditions were employed for the
fabricated ZrO2/CeO2 nanocomposite samples and the best adsorbent were reused for the elimination of AG1
dye.
