In this work, sulfonated chitosan montmorillonite composite (S-CS-MT) beads were synthesized using a microwave irradiation method designed to have a better saving-time procedure. The potency of S-CS-MT as an adsorbent was assessed for the removal of cationic dyes such as methylene blue (MB) from aqueous solution. The batch adsorption experiments indicated that MB adsorption onto S-CS-MT follows the Pseudo-second-order kinetic and Langmuir isotherm model. The maximum extent obtained from the Langmuir isotherm model for MB adsorption was 188.2 mg g⁻¹ at 303 K. The thermodynamic study indicated that the adsorption reaction is favorable and spontaneous in nature. These findings indicated that montmorillonite chitosan grafted with the sulfonate group has the ability and efficacy as biohybrid adsorbent for the adsorption of cationic dyes.

在这项工作中，使用微波辐射法合成了磺化的壳聚糖蒙脱土复合材料（S-CS-MT）珠，以节省时间。评估了S-CS-MT作为吸附剂对从水溶液中去除阳离子染料如亚甲基蓝（MB）的效力。间歇吸附实验表明MB吸附在S-CS-MT上遵循伪二级动力学和Langmuir等温线模型。从Langmuir等温模型获得的MB吸附最大程度为188.2 mg g ^-1在303 K时的热力学研究表明，吸附反应本质上是有利的且自发的。这些发现表明，接枝有磺酸盐基团的蒙脱土壳聚糖具有作为生物杂化吸附剂的能力和功效，用于吸附阳离子染料。
