摘要

本研究优化了以榛子壳为原料制备生物炭，用于吸附水中的扑热息痛、阿莫西林和三氯生。在温度500 ~ 900℃，时间0.5 ~ 2 h，粒径150 ~ 2000 μm 27种条件下制备生物炭。物理化学和仪器分析，以及批量吸附测试，表征了样品。温度（900℃）是影响生物炭性能和吸附性能的最重要因素。吸附数据与非均质等温线模型（包括Sips模型和多层/单层模型）拟合良好。对扑热息痛、阿莫西林和三氯生的最大吸附量分别为19.973、2.992和2.678 mg/g。生物炭基吸附系统与水处理应用将扩大规模。

Influence of pyrolysis conditions on the adsorbent properties of hazelnut shell biochar to remove paracetamol, amoxicillin, and triclosan

This study optimized the production of biochar from hazelnut shells for the adsorption of paracetamol, amoxicillin, and triclosan from water. Biochar was produced under 27 conditions (temperature: 500–900 °C, time: 0.5–2 h, particle size: 150–2000 μm). Physicochemical and instrumental analyses, as well as batch adsorption tests, characterized the samples. Temperature (900 °C) is the most significant factor influencing biochar properties and adsorption performance. Adsorption data fitted well with heterogeneous isotherm models, including the Sips model and multilayer/monolayer models. The maximum adsorption capacities for paracetamol, amoxicillin, and triclosan were 19.973, 2.992, and 2.678 mg/g, respectively. Biochar-based adsorption systems with water treatment applications will be scaled.
