摘要：Magnetic chitosan/graphene oxide (MCGO) was used as a potential adsorbent for fuchsine removal from aqueous systems. The magnetic composite bioadsorbent was characterized by SEM, TEM, FTIR and XRD measurements. The large saturation magnetization (48.93 emu g(-1)) of the synthesized nanoparticles allowed fast separation of MCGO from the liquid suspension. Adsorption data were well studied for adsorption isotherms and kinetics models. The adsorption of fuchsine followed second-order kinetics and was best fitted to the Langmuir adsorption isotherms. MCGO displayed excellent stability over 5 cycles of use and regeneration without incurring significant structural damage or a decrease in fuchsine adsorption properties. These results suggested that the new developed material is a potential adsorbent for the effective removal of dyes from aquatic solutions.
