Abstract :

There is an increasing interest during last years in isolating cellulose nanofibers from unbleached cellulose pulps due to economic, environmental, and functional reasons. In the current work, cellulose nanofibers isolated from unbleached neutral sulfite pulp (RSNF) were compared to those isolated from bleached neutral sulfite pulp in making thin-film ultra-filtration membranes by simple vacuum filtration on hardened filter paper. The prepared membranes were characterized regarding their microscopic structure, hydrophilicity, pure water flux, fouling, and removing lime nanoparticles and oil from oil-in-water emulsion. Using cellulose nanofibers isolated from unbleached pulp resulted in easier formation of thin-film membrane (shorter filtration time) and higher water flux than in case of using nanofibers isolated from bleached fibers, without sacrificing its ability to remove the lime nanoparticles or oil from its emulsion.
