The nanoparticles were characterized by using SEM, (EDX), (AFM), (XRD), (FT-IR), (BET), and Zeta potential. The hydrothermal preparation of zeolite 5A from local kaolin, then characterization, and use of it as a supporting material. The optimum conditions of decolorization of RR120 were studied under experimental parameters such as: [H2O2] = (0.1–20) mmol/L, catalyst dosages = (0.1–1.5) g/L, pH (2.5–9), [RR120 dye] = (15–100) mg/L, reaction time = (0–120) min, and temperature (30–50) °C. The decolorization efficiency of RR120 dye under the optimum reaction conditions by Fenton-like reaction for (GT-Z-Fe/Ni) NPs synthesis by green methods was 99.9%, whereas 96.6% with (Z-Fe/Ni) NPs synthesized by chemical methods. Furthermore, we studied the kinetic and thermodynamic effects of RR120 dye removal by heterogeneous Fenton-like oxidation for GT-Z-Fe/Ni and Z-Fe/Ni NPs by three kinetic models (first-order, second-order, and Behnajady–Modirshahla–Ghanbary (BMG)) and the thermodynamic parameters (∆G0, ∆H0, and ∆S0) at (30, 40, and 50) C°. The results indicate the second-order and the (BMG) are the best models representing the experimental kinetic data of RR120 dye removal, and the reaction is spontaneous and endothermic using GT-Z-Fe/Ni and Z-Fe/Ni nanoparticles. Finally, the comparison of the decolorization efficiency of RR120 dye in optimum conditions using different reaction mechanisms.
