Mesoporous Layered Graphene Oxide/Fe₃O₄/C₃N₃S₃ Polymer Hybrids for Rapid Removal of Pb²⁺ and Cd²⁺ from Water.

ABSTRACT: Mesoporous layered magnetic hybrid GFP2 composed of C₃N₃S₃ polymers, Fe₃O₄ nanoparticles (Fe₃O₄ NPs), and graphene oxide with a mesoporous layered "sandwich"-like structure was successfully explored by in situ simple polymerization tactic for rapid removal of Pb²⁺ and Cd²⁺ from water. It shows good selectivity and high adsorption capacity (277.78 and 49.75 mg/g) for Pb²⁺ and Cd²⁺, respectively. It exhibits the fast adsorption kinetics (>80% elimination efficiency in less than 30 min). The Langmuir isotherm model based on typical monomolecular layer adsorption fits better with the data of adsorption than the Freundlich isotherm model. The adsorption process of GFP2 for Pb
