Frozen salting hydrogels consisting of polydopamine and hydroxyapatite used for oil-water separation
School of Naval Architecture and Marinetime, Zhejiang Ocean University, Zhoushan, 316022, China.
In recent years, with the continuous advancement of industrialization and economic globalization, oil spill pollution incidents have become more and more frequent, among which marine oil pollution is the most prominent. If a large amount of oily sewage is not treated in time, it will pose a great threat to the safety of marine ecology. In this work, natural and biological materials were used to prepare PDA-HAP hydrogel, and the membrane was treated by freezing and salting out to effectively improve the strength of the membrane. The prepared membrane has good flux, can be used repeatedly, and is environmentally friendly. Therefore, this PDA-HAP hydrogel will play a significant role in the field of oily sewage treatment.
