Resumo

Polycarbonate (PC) wastes received from optical (CDs) and digital optical discs (DVDs) were chemical recycled by using diethylene glycol (DEG) and water as an alternative green solvents and magnetite nanomaterials coated with amine modified silica nanoshell (Fe3O4/SiO2/NH2) as the recyclable heterogeneous catalyst to recover bisphenol-A (BPA) as a valuable material in 100% yield and without using harmful reagent and environmental problems. The nano-magnetic heterogeneous catalyst can be recycled for four cycles and used next reaction. The recovered BPA and nanomaterials were examined with transmission electron microscopy (TEM), thermogravimetric analysis (TGA), X-ray powder diffraction (XRD), and spectroscopic methods (1H NMR, 13C NMR, FTIR).
