ABSTRACT Water contamination constitutes a substantial global issue that affects the environment. Adsorption materials have demonstrated huge potential in wastewater treatment. For efficient removal of cationic dye, basic blue 3 (BB3), polypyrrole‐coated cobalt ferrite (PPy@CoFe 2 O 4 ) magnetic nanosorbent is prepared via situ polymerization pyrrole on CoFe nanoparticles. Scanning electron microscopy (SEM) analysis spherical nanoparticles with sizes around 50 nm, which was further supported by XRD data. Zeta‐potential study showed surface charge PPy@CoFe negative alkaline media and positive acidic media. The adsorption system adhered to pseudo‐second‐order kinetic model, equilibrium time being determined at min. Langmuir model accurately simulated isotherms. Under optimal conditions (pH—8.0, volume—30 mL, adsorbent dose—0.67 g/L, 303 K temperature), maximum monolayer capacity PPy/CoFe 130.1 mg g −1 . Even after five desorption–adsorption cycles, efficiency remained above 92%. Negative Δ G ° H indicate spontaneous BB3 onto , decreasing temperature. These findings demonstrate composite highly effective broad applications for treating containing dye.
