A cellulose based hydrophilic, oleophobic hydrated filter for water/oil separation†
Abstract
A hydrated regular cellulose paper filter modified with nanofibrillated cellulose (NFC) hydrogel was successfully fabricated for water/oil separation. The fabricated filter's hydrophilic and oleophobic properties resulted in increased filter life and decreased environmental impact, while displaying water flux of 89.6 L h−1 m−2 with efficiency ≥99% under gravitational force.
