Abstract In this study, kraft pulping and autohydrolysis as combinative pre-treatment were performed on oil palm fronds (OPF-MCC) followed by acid hydrolysis before isolating microcrystalline cellulose (MCC). Further characterization techniques where applied on the isolated MCC for better understanding of its performance. Immobilization technique using fabricated glass system was employed is studying the ability of OPF-MCC as methylene blue adsorbent. The MB equilibrium and kinetics data were best explained by Langmuir and pseudo-second-order models respectively, giving rise to maximum adsorption capacity of 11.42 mg g−1.

通过固定化技术改善油棕叶微晶纤维素的吸附性能

摘要 在本研究中，在分离微晶纤维素 (MCC) 之前，对油棕叶 (OPF-MCC) 进行硫酸盐法制浆和自水解作为组合预处理，然后进行酸水解。进一步的表征技术应用于隔离 MCC，以更好地了解其性能。使用装配玻璃系统的固定技术正在研究 OPF-MCC 作为亚甲基蓝吸附剂的能力。MB 平衡和动力学数据分别由 Langmuir 和伪二级模型最好地解释，产生了 11.42 mg g-1 的最大吸附容量。
