Abstract

Growing environmental concerns have driven the search for sustainable wastewater treatment solutions, particularly for removing persistent synthetic dyes. This study explores hydrogels made from squid pen protein (SPP) and chitosan, biodegradable polymers, for anionic dye adsorption─reactive blue 4 (RB4) and methyl orange (MO). A 50%/50% SPP/chitosan hydrogel was optimal for RB4 adsorption while minimizing chitosan use. Adsorption followed the Langmuir model, with capacities of 151.52 mg/g for RB4 and 54.94 mg/g for MO. Optimal RB4 adsorption conditions were 65 °C, 6 h, pH 7, and 0.2 wt % adsorbent at 300 rpm. Kinetic analysis indicated a pseudo-second-order model, suggesting chemisorption. Characterization (FT-IR, SEM, XPS) revealed functional groups and binding mechanisms, with XPS confirming a nucleophilic attack between the amino groups of chitosan/SPP protein and RB4’s dichlorotriazine moiety. Higher cross-linker content reduced adsorption. This study demonstrates SPP/chitosan hydrogels as a cost-effective, sustainable alternative for wastewater treatment.

更正“鱿鱼笔蛋白壳聚糖基生物复合水凝胶吸附阴离子染料”

日益增长的环境问题促使人们寻找可持续的废水处理解决方案，特别是去除持久性合成染料的解决方案。本研究探索由鱿鱼笔蛋白（SPP）和壳聚糖（可生物降解聚合物）制成的水凝胶，用于吸附阴离子染料─活性蓝4 （RB4）和甲基橙（MO）。50%/50% SPP/壳聚糖水凝胶对RB4的吸附效果最佳，同时壳聚糖用量最少。吸附符合Langmuir模型，RB4的吸附量为151.52 mg/g， MO的吸附量为54.94 mg/g。RB4的最佳吸附条件为65℃，6 h, pH 7，吸附剂浓度为0.2 wt %，转速为300 rpm。动力学分析显示为准二阶模型，表明其为化学吸附。表征（FT-IR， SEM， XPS）揭示了壳聚糖/SPP蛋白的官能团和结合机制，XPS证实了壳聚糖/SPP蛋白的氨基与RB4的二氯三嗪部分之间的亲核攻击。较高的交联剂含量降低了吸附。本研究证明了SPP/壳聚糖水凝胶是一种经济、可持续的废水处理替代方案。
