摘要

复合水凝胶钠接枝聚丙烯酸-co- n -异丙基丙烯酰胺/膨润土（SA-g-P(AA-co-NIPAM/BENT)）是一种吸附去除水溶液中亚甲基蓝（MB）和甲基紫（MV）的有效吸附剂。与钠接枝聚（丙烯酸-co- n -异丙基丙烯酰胺）接枝共聚物SA-g-P（AA-co-NIPAM）相比，在加入0.6 g BENT的情况下，MV和MB的吸附量分别增长了35.5%（从310到420 mg/g）和10.2%（从293到323 mg/g）。MB在SA-g-P（AA-co-NIPAM/BENT）上的吸附是自发的，而MV则是非自发的。此外，两种染料的吸附均满足Freundlich方程和伪二级动力学模型。

Efficient Dye Removal by SA-g-P(AA-co-NIPAM/BENT) Composite Hydrogel

The composite hydrogel sodium graft poly(acrylic acid-co-N-isopropylacrylamide)/bentonite (SA-g-P(AA-co-NIPAM/BENT) emerges as an effective adsorbent to remove methylene blue (MB) and methyl violet (MV) from aqueous solutions through adsorption. Compared with the sodium graft poly(acrylic acid-co-N-isopropylacrylamide) graft copolymer SA-g-P(AA-co-NIPAM), the growth rate in terms of adsorption capacities of MV and MB is 35.5% (from 310 to 420 mg/g) and 10.2% (from 293 to 323 mg/g), respectively, with an incorporation of 0.6 g of BENT. The adsorption of MB on SA-g-P(AA-co-NIPAM/BENT) is spontaneous while MV is nonspontaneous. In addition, adsorption of both dyes satisfies the Freundlich equation and the Pseudo second-order kinetic model.
