This paper studies the synthesis, characterization, and application of ZnFe2O4 nanoparticles for removal rhodamine b dye from aqueous media. Utilizing combustion procedure, were synthesized using two different fuels: glutamine (SG) L-arginine (SA). In addition, characterized through various techniques, including Fourier transform infrared (FTIR), X-ray diffraction (XRD), field emission scanning electron microscope (FE-SEM), energy-dispersive (EDX), high resolution transmission (HR-TEM), Brunauer-Emmett-Teller (BET) surface area analysis. XRD analysis verified creation a cubic spinel structure without any contaminants, revealing average crystallite sizes 43.72 29.38 nm SG SA samples, respectively. The FTIR spectra exhibited peaks indicative metal-oxygen bond stretching, verifying presence formation. Elemental via EDX confirmed stoichiometric composition typical zinc ferrite. FE-SEM imaging displayed that samples are composed particles with irregular spherical shapes, measuring diameters 135.11 59.89 nm, Furthermore, BET is 60 85 m2/g, maximum adsorption capacity sample (409.84 mg/g) towards was higher than (279.33 mg/g), which ascribed to its larger porosity. Kinetic equilibrium revealed process onto followed Langmuir isotherm pseudo-second-order model.
