Industrial sectors are main responsible for continually releasing of harmful compounds in the form of wastewater. The potential utilization of bio-waste materials has received great attention to minimize the serious environmental issues. Therefore, the present research is focused to develop an Elaeis guineensis/polyvinyl alcohol/carbon nanotube (EG/PVA/CNT) composite via a simple polymerization method and tested to remove the dye from aqueous solutions. Field emission scanning electron microscopy (FE-SEM) and Fourier transform infrared spectroscopy (FTIR) characterizations were selected to confirm the morphology and chemical structures of composites. The water content measurement and swelling characteristics of EG/PVA/CNT were also elaborated. The evaluation of composites was explored through the elimination of methylene blue (MB) in a batch adsorption scheme including EG loading, pH of MB aqueous solutions, contact time, initial concentration of MB solutions, adsorbent dose and solution temperature. The results revealed that EG-based adsorbents have superior adsorption efficiency of 92.44%. The adsorption kinetics was well explained by pseudo-second-order model, while in adsorption isotherms, Langmuir model was appropriate to demonstrate the MB adsorption data giving superlative removal aptitudes. The thermodynamic results revealed that adsorption onto EG/PVA/CNT was favorable, spontaneous and exothermic in nature, while activation energy informed the physical type of adsorption process. The adsorption mechanism of MB onto EG/PVA/CNT was also proposed. Moreover, EG/PVA/CNT was in stable form with good adsorption capacity and could easily be recycled. Based upon the present research, a strong strategy between EG, CNT and PVA could successfully develop an economical adsorbent for the treatment of different effluents.

工业部门主要负责以废水的形式不断释放有害化合物。生物废料的潜在利用受到了极大的关注，以尽量减少严重的环境问题。因此，本研究的重点是通过简单的聚合方法开发一种豚草/聚乙烯醇/碳纳米管（EG/PVA/CNT）复合材料，并测试从水溶液中去除染料。选择场发射扫描电子显微镜 (FE-SEM) 和傅里叶变换红外光谱 (FTIR) 表征来确认复合材料的形态和化学结构。还详细阐述了EG/PVA/CNT 的含水量测量和溶胀特性。通过在批量吸附方案中消除亚甲蓝 (MB) 来探索复合材料的评估，包括 EG 负载、MB 水溶液的 pH 值、接触时间、MB 溶液的初始浓度、吸附剂剂量和溶液温度。结果表明，基于EG的吸附剂具有92.44%的优异吸附效率。吸附动力学由伪二级模型很好地解释，而在吸附等温线中，Langmuir 模型适用于证明 MB 吸附数据提供最高级的去除能力。热力学结果表明，在 EG/PVA/CNT 上的吸附是有利的、自发的和放热的，而活化能决定了吸附过程的物理类型。还提出了MB在EG/PVA/CNT上的吸附机理。而且，EG/PVA/CNT 形态稳定，吸附能力强，易于回收利用。基于目前的研究，EG、CNT 和 PVA 之间的强大策略可以成功开发一种经济的吸附剂，用于处理不同的废水。
