Abstract:

In order to solve the adsorption problem of methylene blue (MB) in dyeing wastewater, a cellulose nanofiber(CNF) aerogel was prepared from rice straw CNF suspension by freezing and thawing gel, displacing with tert-butanol solvent and freeze drying with liquid nitrogen. The morphology structure of the aerogel as well as its adsorption capacity to MB was characterized. The influences of adsorbent quality and solution pH value on the adsorption performance were also investigated. The adsorption mechanism was discussed by adsorption kinetics and adsorption isotherm model. The results show that the CNF aerogel obtained by freeze-drying of tert-butanol has a three-dimensional network structure which contains a large number of spider-like fibers with a diameter of 6-26 nm. The aerogel exhibits a porous structure with a specific surface area of 52.25 m2/g, and an average pore size of 28.82 nm. The pseudo-second-order adsorption kinetic and Freundlich adsorption isothermal model are more suitable for describing the adsorption process of methylene blue on CNF aerogel, with the theoretical maximum adsorption of 196.08 mg/g.
