Hydrogel beads based on oxidized corn starch cross-linked with gelatin for tartrazine adsorption from aqueous environments

Abstract

The adsorption approach is considered as the most effective method of removing dyes from effluents, which among new synthetic materials become high-profile as adsorbents in recent years. This work provides a noble synergistic hydrogel beads based on oxidized corn starch (OCS) and gelatin (G). The OCS and G can form three-dimensionally cross-linked networks owing to Schiff’s base formation. This work also proved that the form of hydrogel beads can be implemented in the synergistic materials for removing dyes from effluents, which has so far been neglected in the literature.
