dc.description.abstractThe evaluation of kinetic adsorption process of sulfonated carbon-derived from Eichhornia crassipesin the adsorption of methylene blue dye from aqueous solution has been carried out. The sulfonated car-bon-derived fromE. crassipes(EGS-600) was prepared by carbonation of E. crassipespowder at 600 °C for 1 h, followed by sulfonation with concentrated sulfuric acid for 3 h. The physical properties of the adsorbents were characterized by using Fourier transform infrared spectroscopy, X-ray diffraction (XRD), scanning electron microscopy (SEM), and nitrogen adsorption-desorption studies. Adsorption study using methylene blue dye was carried out by varying the contact time and initial dye concentra-tion for investigated kinetics adsorption models. The effect of varying temperature was used to deter-mine the thermodynamic parameter value of ?G, ?H, and ?S. The results showed that the equilibrium adsorption capacity was 98% when EGS-600 is used as an adsorbent. The methylene blue dye adsorp-tion onto adsorbent takes place spontaneity and follows a pseudo-second-order adsorption kinetic model.Copyright © 2019 BCREC Group. All rights reserved
