摘要：
A sodium alginate/microcrystalline cellulose (SA/MCC) composite hydrogel was synthesized using sodium alginate (SA) and microcrystalline cellulose (MCC) as raw material. The structure of the prepared hydrogel was characterized, and the adsorption properties, model and mechanism of the hydrogel for aqueous methyl orange (MO) and methylene blue (MB) were studied. The results showed that the optimal pH of SA/MCC-20 removing MO and MB were 2 and 12, respectively. The adsorption model was more consistent with the pseudo-second-order model and Langmuir model, and the maximum adsorption capacity of MO and MB could reach 331.25mg/g and 253.31mg/g, respectively. By changing the pH of the aqueous solution, both MO and MB could achieve effective adsorption and desorption on SA/MCC-20 for recycling. After 5 times of sorption-desorption cycles, the desorption efficiency of MO and MB of SA/ MCC-20 remained 91.52% and 85.41% at optimal pH. SA/MCC possessed excellent adsorption capacity for MO and MB, and the adsorption mechanism mainly included electrostatic attraction, van der Waals force, hydrogen bonding, π-π stacking, pore diffusion and filling, etc, and chemisorption played a leading role with the auxiliary of physical adsorption. © 2024 Chemical Industry Press Co., Ltd..
