Super hydrophilic Sodium Alginate Coating on the Surface of Polyvinylidene Fluoride via Freezing and Salting-out for Achieving Emulsion Oil Purification

Abstract In recent, oily wastewater as a special contaminant has seriously impacted the ecological environment. this work, nature and green materials are used to prepare SA-PVDF membrane taking freezing salt out super hydrophilic modifying. Therefore, obtained exhibited good flux, excellent recyclability, superior separation efficiency. More importantly, filter was green, eco-friendly, cost-affordable. such simple, universal, facile method could be in other organic inorganic for preparing membranes, which plays significant role construing novel filtration membranes remove oil from practical life.
