Study of methylene blue adsorption in aqueous solution using alginate-bentonite beads

Abstract

Sodium alginate is a biodegradable polymer that is generally regarded as a safe substance, because of its nontoxic properties and gel-enhancing properties (He et al. in Appl Clay Sci 109–110:68–75, 2015). The addition of Bentonite in gel forming alginate polymers produces an excellent matrix that increases the compound adsorption properties.
