Alginates as Green Flocculants for Metal Oxide Nanoparticles

Abstract Flocculation is used for the removal or separation of colloids, e.g. in water treatment and mineral processing. Alginates are linear, anionic biopolymers composed mannuronic (M) guluronic (G) acids. The relative amount distribution M G impact ion-binding gel-forming properties polymer, but still no one has yet addressed alginate composition on flocculation nanoparticles particles. Our results showed that was important flocculation, especially when Ca 2+ as activating ion. With Ce 3+ ion, shape size flocs were affected by acetylation. This work expands knowledge about behavior alginates demonstrates both bacteria- algae-derived can be potential biodegradable flocculants ultrafine particles processing industry.
