Synthesis of SnFe2O4@ZnO nanocomposite decorated with the reduced graphene oxide (rGO) showing highly efficient dye adsorption properties was successfully developed. Prior to the decoration process, the SnFe2O4@ZnO were synthesized by low-cost and simple co-precipitation method. The decoration of SnFe2O4@ZnO with rGO was conducted via facile ultrasonication and consecutive heat treatment. Adsorption efficiency of as-synthesized SnFe2O4@ZnO@rGO was identified using UV-Visible spectrometer under dark ondition and found to reach 90% after 20 min based on 16 wt.% rGO. The reusability of SnFe2O4@ZnO@rGO-16 was excellent because of the magnetic fatures SnFe2O4 which can be recycled using a magnet. In addition, the adsorption quilibrium was analyzed and represented via Langmuir, Freundlich and Dubinin-Radushkevich isotherms models. The kinetics data resented good correlation coefficient (R2) values of 0.993 orresponding to Freundlich isotherm models. The SnFe2O4@ZnO@rGO-16 nanocomposites were identified to
own large surface area by BET 120.33 m2/g. The anocomposites were characterized by XRD, SEM, FTIR, RAMAN, PL, BET and Zeta Potential.
