An innovative hybrid biosorbent composed of nano ZnO and marine macro algae Jania rubens embedded in an alginate/PVA matrix: insights into Pb²⁺ removal in water

Abstract

Nanoparticles of zinc oxide (ZnO) combined with Jania rubens (JR) biosorbent have been embedded in a sodium alginate (SA)–polyvinyl alcohol (PVA) matrix. This hybrid biosorbent has been characterized by FTIR,...

Novel luminescent hierarchical porous hydrogels with a three-dimensional interconnected network structure from feather keratin crosslinking reaction

“…Algae have been found to be a potential multi-functional material due to their cell walls with functional groups such as carboxylate, amino, hydroxyl, and phosphate, which play a pivotal part in grafting, and adsorbing. 20 Here, we demonstrated that keratin and unmodified SP were crosslinked successfully to obtain keratin-seaweed hydrogels with megascopic porous networks. Compared with FK-2, the rough, fluffy, and relatively larger porous structure of FK-SP was observed (Fig.…”
