摘要: A novel β-cyclodextrin–chitosan–graphene oxide (β-CD–CS–GO) composite material was fabricated, and its application as excellent adsorbents for the removal of manganese ion [Mn(II)] illustrated. The structure morphology β-CD–CS–GO were characterised by Fourier transform infrared spectroscopy, scanning electron microscopy, X-ray diffraction, thermogravimetric analysis differential calorimetry. composites could efficiently remove Mn(II) from aqueous solution. adsorption experiment carried out, optimum experimental conditions determined. highest efficiency can reach 96% at 0.020 g mL− 1 β-CD–CS–GO, temperature 25°C time 3 h. kinetics system investigated, data well followed pseudo-second order equation. equilibrium used to simulate Langmuir Freundlich isotherm models, results show that in correlat...
