In this study, the influence of carboxymethyl cellulose(CMC) on the structure and adsorption behavior of TEMPO-oxidized cellulose nanofibril(TOCN) based aerogel was investigated. The rheological and precipitation observations strongly supported the prevention ofTOCN hornification by CMC. The SEM images of prepared aerogel confirmed the dense pore structure owing to low hornification of TOCN. The adsorption behaviors of the fabricated aerogels were isothermally and kinetically studied using methylene blue(MB) as a cationicmodel dye. CMC added TOCN aerogel showed the highest maximum adsorption capacity (208.07 mg·g-1) towards MB due to the dense pore structure and maintained the adsorption performance after 5 repeated adsorption cycles. The effect of TOCN hornification was animportant parameter on the TOCN aerogel structure and adsorption performance.
