In this paper, we report new findings on the synthesis of carbon microspheres from a biomass precursor (Sabal palmetto) using one-step hydrothermal carbonization (HTC) process. The carbonization process involved predominantly dehydration process with partial occurrence of decarboxylation. The microspheres were analyzed using elemental analysis and scanning electron microscopy (SEM). The produced microspheres were applied as adsorbents for sorption of an industrial dye (methylene blue) in which the data showed good fitting to the Langmuir model. The sub-micron-sized microspheres exhibited interesting textural characteristics—relatively low surface areas and porosities with presence of oxgenated functional groups (total = 0.4 to 0.5 mmol/g) on the surface. The work presented in this contribution involves themes on sustainable usage of resources (i.e., biomass), production of useful industrial microparticles, and direct application in wastewater purification.

萨巴尔棕榈(Sabal palmetto)生物质水热碳化合成碳微球吸附亚甲基蓝
在本文中,我们报告了从生物质前体(Sabal palmetto )合成碳微球的新发现。) 使用一步水热碳化 (HTC) 工艺。碳化过程主要涉及脱水过程,部分发生脱羧。使用元素分析和扫描电子显微镜(SEM)分析微球。所生产的微球用作吸附工业染料(亚甲蓝)的吸附剂,其中数据显示与朗缪尔模型非常吻合。亚微米大小的微球表现出有趣的结构特征——相对较低的表面积和孔隙率,表面存在氧化官能团(总含量 = 0.4 至 0.5 mmol/g)。本文稿中介绍的工作涉及资源(即生物质)的可持续利用、有用的工业微粒的生产以及废水净化中的直接应用等主题。
