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. These results highlight the potential of the modified sponge as an effective sorbent for oily wastewater treatment.

花状氧化锌和硬脂酸对超疏水磁性三聚氰胺海绵进行浸涂改性，用于油水分离。

石油泄漏和含油工业废水的日益增加，提高了对有效油水分离的需要。本研究采用ZnO、硬脂酸和Fe3O4纳米颗粒浸渍包膜的方法制备了磁性超疏水三聚氰胺海绵。通过XRD、FESEM、EDX、FT-IR、AFM、VSM和水接触角（160.96˚±0.65˚）测试表明其具有优异的性能。吸附量为36.12±1.9 ~ 83.71±2.8 g·g-1，分离效率为97.82±1.3 ~ 99.83±1.7%。并对其在实际工业废水中的除油性能进行了评价。此外，海绵具有可重复使用性和高效分离乳化油滴的特点。这些结果突出了改性海绵作为含油废水处理有效吸附剂的潜力。
