Superhydrophobic magnetic melamine sponge modified by flowerlike ZnO and stearic acid using dip coating method for oil and water separation.

ABSTRACT: The increasing occurrence of oil spills and industrial effluents containing oil have heightened the need for effective oil-water separation. This study developed a magnetic superhydrophobic melamine sponge using a dip-coating method with ZnO, stearic acid, and Fe₃O₄ nanoparticles. Characterization via XRD, FESEM, EDX, FT-IR, AFM, VSM, and water contact angle measurements (160.96˚ ± 0.65˚) revealed its excellent properties. The sponge demonstrated a sorption capacity of 36.12 ± 1.9 to 83.71 ± 2.8 g·g^-1 and separation efficiency ranging from 97.82 ± 1.3 to 99.83 ± 1.7%. Its performance in removing oil from real industrial effluent was also evaluated. Additionally, the sponge exhibited reusability and high efficiency in separating emulsified oil droplets. Thes
