Abstract In this research, batch adsorptions of methylene blue (MB) dye using physically and chemically activated Ceiba pentandra seeds (PACP and CACP) have been inspected. SEM-EDAX and XRD analysis for adsorbents have been studied. The acquired consequences of isotherm and kinetic investigations exhibit that Freundlich and pseudo-first order models demonstrated better association. Langmuir adsorption capacity of PACP and CACP was observed as 324.01 and 469.4 mg/g, respectively. Sticking probability for MB dye was found to be high. This adsorption process was unconstrained and exothermic in nature. This modified materials has an ability to remove MB dye from polluted water.

物理/化学改性木棉籽去除水溶液中亚甲蓝染料的建模与分析

摘要 在这项研究中，已经检查了使用物理和化学活化木棉种子（PACP 和 CACP）对亚甲基蓝 (MB) 染料的批量吸附。已经研究了吸附剂的 SEM-EDAX 和 XRD 分析。等温线和动力学研究的获得结果表明 Freundlich 和伪一级模型表现出更好的关联。观察到 PACP 和 CACP 的朗缪尔吸附容量分别为 324.01 和 469.4 mg/g。发现 MB 染料的粘附概率很高。这种吸附过程在本质上是不受约束的和放热的。这种改性材料能够从污水中去除 MB 染料。
