Abstract:
The Magnetic Cellulose Nanocrystal-Modified Diatomite (MCNCD) composite was synthesized and its adsorption performance for removal of Methylene Blue (MB) dye from aqueous solutions was investigated. The as-prepared MCNCD samples were characterized by Fourier transform infrared spectroscopy, scanning electron microscopy, thermal gravimetric analyzer, and vibration sample magnetometer, respectively. The adsorption parameters such as temperature, initial concentration of MB, adsorption time, and pH, were studied. The adsorption isotherms and kinetics were established. The results showed that adsorption isotherm and kinetics fitted well to the Langmuir model and pseudo-second-order model, respectively. Furthermore, the as-prepared MCNCD samples can be reused/ recycled after regeneration, with an adsorption capacity of 46.21 mg/g after six cycles.
