Abstract

This study aimed to develop four adsorbents, neat and activated, from the cardoon leaves and stems. The developed adsorbents were first analyzed to determine the surface acid–base properties using Boehm’s method, pH at zero charge point, iodine and methylene blue values, and moisture, ash, and fixed carbon contents. They were also characterized by scanning electron microscopy coupled with energy-dispersive X-ray analysis, X-ray diffraction, Fourier transform infrared absorption spectroscopy, thermogravimetric analysis, and inductively coupled plasma atomic emission spectroscopy. After that, these adsorbents were applied for adsorption of an organic dye “brilliant green” (BG), and the effect of various parameters on the adsorption efficiency was evaluated. The obtained results revealed the differences between the adsorbents derived from the neat cardoon leaves and stems and their activated carbon in terms of properties and BG adsorption efficiency.

基于牛蒡废弃物的新型生态吸附剂的开发与表征：应用于绿色吸附

本研究旨在利用牛蒡的叶子和茎开发四种吸附剂，包括纯吸附剂和活性吸附剂。首先对所开发的吸附剂进行了分析，利用玻姆法确定了其表面酸碱特性、零电荷点的 pH 值、碘值和亚甲基蓝值，以及水分、灰分和固定碳含量。此外，还利用扫描电子显微镜结合能量色散 X 射线分析、X 射线衍射、傅立叶变换红外吸收光谱、热重分析和电感耦合等离子体原子发射光谱对这些吸附剂进行了表征。然后，将这些吸附剂用于吸附有机染料 "艳绿"（BG），并评估了各种参数对吸附效率的影响。结果表明，从纯净的豆蔻叶和茎中提取的吸附剂与其活性炭在性质和 BG 吸附效率方面存在差异。

期刊介绍： Open Chemistry is a peer-reviewed, open access journal that publishes original research, reviews and short communications in the fields of chemistry in an ongoing way. The central goal is to provide a hub for researchers working across all subjects to present their discoveries, and to be a forum for the discussion of the important issues in the field. The journal is the premier source for cutting edge research in fundamental chemistry and it provides high quality peer review services for its authors across the world. Moreover, it allows for libraries everywhere to avoid subscribing to multiple local publications, and to receive instead all the necessary chemistry research from a single source available to the entire scientific community.
