Windmill palm leaf sheath fiber, Activated carbon, Methylene blue, Adsorption isotherm, Kinetics, thermodynamics


Windmill palm sheath fiber (WPF) is an abundant agricultural by-product and useful resource. To increase its valuable qualities and usefulness, we proposed to prepare WPF-based activated carbon (WPFAC) as a novel adsorbent for adsorbing methylene blue (MB), with the specific aims for pollution treatment. The porous features of WPFAC were assessed based on nitrogen adsorption, and the adsorption capacity was studied by investigating the effect parameters of contact time, initial concentration, pH and temperature. Research results show a combination microporous and mesoporous structure of WPFAC with BET surface of 668.81 m2/g. WPFAC exhibits excellent adsorbing performance, and the maximum monolayer adsorption capacity is up to 51.78 times higher than other absorbents. Meanwhile, the adsorption capacity increased accordingly as the parameters increase. For better understanding the adsorption behavior, isotherms, kinetics and thermodynamic were studied by using the equilibrium data. Investigation results illustrated the equilibrium data were well consistent with the Langmuir isotherm, with a maximum monolayer adsorption capacity of 253.16, 289.85, and 303.95 mg/g at 30, 40, and 50 °C, respectively. The adsorption kinetics followed the pseudo-second-order kinetic model. Thermodynamic parameters: standard enthalpy (ΔH0), standard entropy (ΔS0), and standard free energy (ΔG0) indicated an endothermic and spontaneous absorbing process. WPFAC is a promising material which has high utility values for its amazing adsorption capacity.
