Abstract :In this work, the synthesis and characterization of [insert ignore into journalissuearticles values(Fe-Zn NPs);/C] were carried out and then it was evaluated as a heterogeneous catalyst in the Fenton-like reaction of NBB. The characterization studies showed that the synthesized composite material had amorphous structure and it contained C, O, Fe, and Zn elements. Also, it was observed by SEM analysis that iron-zinc nanoparticles insert ignore into journalissuearticles values(Fe-Zn NPs); formed between the carbon microspheres indicating the hydrochar structure. The Fenton-like removal ability of [insert ignore into journalissuearticles values(Fe-Zn NPs);/C] was also evaluated and the results demonstrated that [insert ignore into journalissuearticles values(Fe-Zn NPs);/C] could be a promising Fenton-like catalyst for the removal of NBB dyestuff from aqueous solutions. The optimum experimental conditions of this Fenton-like reaction were determined to be 3.0 of initial pH, 50 mM of H2O2 concentration, 40 ⁰C of temperature, and 0.25 g/L of catalyst concentration. The reaction order and rate constant were found as 0.5669 and 4.45, respectively.
