Multifunctional crosslinked chitosan/nitrogen-doped graphene quantum dot for wastewater treatment

The fabrication of multifunctional nanomaterial for the adsorption of different types of pollutants is a challenge and could be a solution for many problems associated with wastewater treatment. This current study propose the use of crosslinked chitosan/nitrogen doped-graphene quantum dot nanocompos...
