Abstract

Highlights • Separation of nanoscale emulsion is extremely difficult due to small droplet sizes. • Nanoscale emulsions pose a significant environmental risk. • Recent approaches include novel membranes, chemicals, and magnetic nanoparticles. • Techniques suffer from low flux, low separation efficiency, and environmental risks. • Research into scalable, green techniques is needed to meet industry demands.
