Abstract

Hydrogel nanobeads include an ionically crosslinked sulfated polysaccharide biopolymer such as a carrageenan. In an embodiment, the hydrogel nanobeads comprise kappa carrageenan (κCg) and a metal ion crosslinking agent. In an embodiment, the metal ion crosslinking agent includes a metal ion selected from the group consisting of Zn, Fe, Fe, and Ti. The hydrogel nanobeads can be used for removal of pollutants in wastewater.
