【 摘 要 】

n this work, the synthesis and characterization of [(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 (Fe-Zn NPs) formed between the carbon microspheres indicating the hydrochar structure. The Fenton-like removal ability of [(Fe-Zn NPs)/C] was also evaluated and the results demonstrated that [(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.
