Abstract

The adsorption of methylene blue dye using biosorbents based on humic acid cross-linked cellulose has been carried out. The adsorbent HA/Cel-Epi characterized using FTIR, XRD, and SEM spectroscopy. The results of characterization using FTIR indicated that adsorbents HA/Cel-Epi had active functional groups among others ‒OH, ‒C=O, and ‒COOH. XRD result confirmed that diffraction peaks on the area of 2θ around 11.83; 20.27; 21.90; and 28.28º. SEM results showed that the adsorbent surface had irregular shape pores size. The optimum condition interaction of HA/Cel-Epi MB occurred in the pH range of 6-8, with a solution concentration of 250 mg L-1, and a contact time of 120 min. The adsorption of MB by HA/Cel-Epi followed pseudo-second-order kinetics model and Freundlich isotherms with the adsorption capacities of MB at 324.43 mg g-1 . © 2021 Trans Tech Publications Ltd, Switzerland.
