In this study, a new cellulose-based nano-adsorbent was synthesized using a simple method. The synthesized adsorbent was characterized using FT-IR, FESEM and EDX analyses. Adsorption characteristics of epoxy-triazine-modified cellulose nan-adsorbent were compared with cellulose for the removal of malachite green dye from aqueous media. The effects of surface improvement on the adsorption of organic adsorptive were studied by considering various parameters such as contact time, adsorbent dosage, pH, and temperature. The obtained results indicated that the pseudo-second-order model and Freundlich isotherm model well describe the dye adsorption process on the nano-adsorbent. The maximum adsorption capacity of MG on the nano-adsorbent at 45 ˚C was found to be 49.26 mg/g. Furthermore, the calculated thermodynamic parameters showed that the adsorption process of the MG dye was endothermic and associated with an increase in entropy.
