Synthesis and characterization of Schiff-base based chitosan-g-glutaraldehyde/NaMMTNPs-APTES for removal Pb2+ and Hg2+ ions

In this paper, a new Schiff base based on porous chitosan-glutaraldehyde /montmorrilonite nanoparticles modified with 3-aminopropyl triethoxysilane (PCG/ NaMMTNPs-APTES) nanocomposite was prepared using cationic copolymerization technique. The structure of the biosorbents was characterized using FTIR, SEM, TEM, DSC, TGA/DTG, BET,…
