Facile synthesis of sustainable Gum karaya-sodium alginate interpenetrated biohydrogels decorated with aluminum oxide hydroxide-nickel oxide nanoparticles for superior removal of Congo red from wastewater.
An eco-friendly hybrid biohydrogel adsorbent, namely GK-SA/AlO(OH)-NiO (Gum Karaya-Sodium Alginate/ Aluminum oxide hydroxide-Nickel Oxide nanocomposite), was successfully synthesized via a green ionic gelation technique followed by Ca2+ crosslinking-bead formation and subsequent thermal stabilization of the embedded na...
