| description | Indigo carmine dye falls into the category of toxic chemicals, potentially leading to irritation and allergic reactions in certain individuals. Thus, this study employed the Pechini sol–gel strategy to easily produce CoFe<sub>2</sub>O<sub>4</sub> nanoparticles, which serve as an effective adsorbent for the disposal of indigo carmine dye from aqueous solutions. The maximum adsorption capacity of CoFe<sub>2</sub>O<sub>4</sub> for indigo carmine dye was determined to be 421.94 mg/g. The synthesized CoFe<sub>2</sub>O<sub>4</sub> nanoparticles exhibited an average crystallite size of 18.75 nm. SEM analysis revealed that these nanoparticles were nearly spherical, with an average grain size of 198.32 nm. Additionally, TEM analysis indicated a fully agglomerated spherical morphology for the CoFe<sub>2</sub>O<sub>4</sub> sample, with an average diameter of 15.37 nm. The EDS spectrum confirmed that the synthesized CoFe<sub>2</sub>O<sub>4</sub> nanoparticles consisted of Co, Fe, and O elements, with respective weight percentages of 17.82%, 49.46%, and 32.72%. The removal of indigo carmine dye by the synthesized CoFe<sub>2</sub>O<sub>4</sub> is spontaneous, chemical, exothermic, closely fitting the pseudo-second-order kinetic model, and demonstrating a strong concordance with the Langmuir equilibrium isotherm. |
