Abstract

Eco-friendly ethanol (EtOH)-water (H₂O) mixture has demonstrated huge potential in the textile industry. However, the uncontrolled discharge of dye-contaminated EtOH-H₂O mixture to the ecosystem has numerous adverse effects. Herein, a sustainable approach utilizing the agricultural waste biomass-Juncus effusus (JE) to synthesize magnetic cellulose JE powders (M-JEPs) has been proposed for purification of dye-contaminated EtOH-H₂O mixture. Batch experiments and physical-chemical analyses were performed to explore the adsorption performance and mechanism. The as-prepared cellulose M-JEPs exhibited ultrafast adsorption performance, which can reach the adsorption equilibrium within 10 min. The adsorption isotherms and kinetics demonstrated that the adsorption fitted well with the Langmuir isotherm and pseudo-second-order kinetic models, exhibiting the maximum adsorption capacity towards C.I. Reactive Red 195 and C.I. Reactive Blue 222 of 58.21 mg/g and 86.06 mg/g at the temperature of 303K. These findings indicate the feasibility of using cellulose M-JEPs for rapid purification of the dye-contaminated EtOH-H₂O mixture.
