Abstract

In this study, nano-porous carbon was completely obtained from oil palm leaves (OPL) by hydrothermal pretreatment with chemical activation, using potassium hydroxide (KOH) as an activating agent. Potassium hydroxide was varied, with different ratios of 1:0.25, 1:1, and 1:4 (C: KOH; /) during activation. The physical morphology of nano-porous carbon has a spongy, sponge-like structure indicating an increase in specific surface area and porosity with the increasing amount of KOH activating agent. The highest specific surface area of OPL nano-porous carbon is approximately 1685 m·g, with a total pore volume of 0.907 cm·g. Moreover, the OPL nano-porous carbon significantly showed a mesoporous structure designed specifically to remove water pollutants. The adsorptive behavior of OPL nano-porous carbon was quantified by using paraquat as the target pollutant. The equilibrium analyzes were explained by the Langmuir model isotherm and pseudo-second-order kinetics. The maximum efficiency of paraquat removal in wastewater was 79%, at a paraquat concentration of 400 mg·L, for 10 min in the adsorption experiment. The results of this work demonstrated the practical application of nano-porous carbon derived from oil palm leaves as an alternative adsorbent for removing paraquat and other organic matter in wastewater.

摘要

在这项研究中，通过水热预处理并用化学活化剂氢氧化钾 (KOH) 对油棕叶（OPL）进行完全处理，得到了纳米多孔碳。在活化过程中，KOH 的用量不同，比例分别为 1:0.25、1:1 和 1:4（C：KOH；/）。纳米多孔碳的物理形态呈海绵状、海绵状结构，表明随着 KOH 活化剂用量的增加，比表面积和孔隙率增加。OPL 纳米多孔碳的比表面积高达约 1685 m·g，总孔体积为 0.907 cm·g。此外，OPL 纳米多孔碳明显表现出特定设计用于去除水污染物的中孔结构。通过使用百草枯作为目标污染物来量化 OPL 纳米多孔碳的吸附行为。平衡分析通过 Langmuir 等温模型和伪二阶动力学进行解释。在吸附实验中，当百草枯浓度为 400mg·L，吸附时间为 10min 时，废水中百草枯的去除效率最高可达 79%。这项工作的结果表明，油棕叶衍生的纳米多孔碳作为替代吸附剂，可用于去除废水中的百草枯和其他有机物，具有实际应用前景。
