Removal of organic herbicides from aqueous solution by ionic liquid modified chitosan/metal-organic framework composite
Copyright © 2020. Published by Elsevier B.V..
The novel ILCS/U-X powder materials were fabricated by depositing UiO-66 on ionic liquid modified chitosan, and different doping ratio materials were used to adsorb 2,4-dichlorophenoxyacetic acid in aqueous solution. The samples were characterized by X-ray powder diffraction, Fourier transform infra-red, X-ray photoelectron spectroscopy, Scanning electron microscopy, Brunauer-Emmett-Teller, Barrette-Joyner-Halenda, Thermal gravimetric analyzer, Energy dispersive spectrometer and Zeta potential. Adsorption experiments revealed that temperature and pH have a great influence on adsorption, and all adsorbents have the highest adsorption at low temperature and weak acid. The dependence of ILCS/U-X on pseudo-second order model and Temkin model was observed. Compared to other ratios, the Micro-doped ILCS/U-10 has the largest adsorption capacity and can quickly complete adsorption within 60 min. ILCS/U-10 also has good stability and can be recycled many times. Hydrogen bonding and electrostatic interaction are the two most important forces that dominate adsorption.
