Modification Of PVDF Membrane Using Lignin And Calcium Carbonate For Oily Water Separation To Be Used In Water Dispenser

Lignin is the world's second most abundant biopolymer and source of aromatic structures which consist of plenty of hydrophilic groups. Lignin have the ability to be used as a hydrophilic promoter in membrane fabrication due to its property which able to improve the hydrophilicity and antifoul...
