β-Cyclodextrin carbon-based nanoparticles with a core-shell-shell structure for efficient adsorption of crystal violet and bisphenol A
文献摘要：
Textile wastewater contains highly toxic,nondegradable,carcinogenic organic pollutants,causing severe damage to the ecological environment.In this work,β-cyclodextrin carbon-sphere-based nanocompos-ite (CS/SiO2@β-CD) with a core-shell-shell configuration was prepared by hydrothermal synthesis and subsequent sedimentation-azeotropic distillation with SiO2 as intermediate layer for the removal of crystal violet (CV) and bisphenol A (BPA).The chemical structure and morphology of the CS/SiO2@β-CD were characterized by FT-IR,SEM and TEM.The effects of contact time,pH,temperature and initial concentration of the absorbates on the adsorption property were explored.The CS/SiO2@β-CD showed excellent adsorption capacity on CV and BPA,and the maximum adsorption capacity was 87.873 mg g-1 and 165.095 mg g-1,respectively.Their adsorption process was in line with the pseudo-second-order and pseudo-first-order kinetic models,respectively.The adsorption thermodynamics could be better fit-ted by Langmuir model than by Freundlich model.The calculated thermodynamic parameters (-△G0,△S0 and △H0) illustrated the adsorption of CV was endothermic,in contrast,the adsorption of BPA was exothermic process.Furthermore,the CS/SiO2@β-CD showed excellent recovery performance,making it a potential adsorbent for the practical treatment of textile wastewater.
