摘要

摘要: 以美人蕉为原料通过热解制备生物炭,并通过HNO₃和KOH对其浸渍改性制备了酸、碱改性生物炭,采用扫描电镜、比表面积及孔径分析仪和傅里叶红外光谱对制备的生物炭进行表征,研究了生物炭对磺胺甲噁唑(SMX)的吸附性能和机理,同时考察了pH值和生物炭投加量对SMX吸附效果的影响。结果表明:相较于未改性生物炭,酸碱改性后生物炭比表面积大幅提高,孔道结构更加发达,吸附性能显著提升。3种生物炭对SMX的吸附过程均符合准二级动力学模型;未改性和碱改性生物炭的等温吸附符合Freundlich模型,酸改性生物炭吸附等温线更符合Langmuir模型。吸附热力学表明,3种生物炭对SMX的吸附均为自发的吸热过程。pH值和生物炭投加量对3种生物炭吸附SMX的效果影响显著。吸附过程受到孔隙填充、氢键、π-π EDA以及静电相互作用的共同影响。

Abstract: In this paper, biochar was prepared by pyrolysis with Canna indica as raw material, and then modified with HNO₃ and KOH, respectively. The structures and properties of the biochar were characterized by using scanning electron microscopy (SEM), specific surface area and porosity analyzer (SSAP), and Fourier transform infrared spectroscopy (FTIR). The adsorption performance and mechanism of sulfamethoxazole (SMX) by biochars were investigated, and the effects of pH and biochar dosage on the adsorption of SMX were investigated as well. The results showed that compared with the unmodified biochar, the specific surface area of acid/alkali modified biochar was greatly increased, the pore structure was deeply developed, and the adsorption performance was significantly improved. The adsorption process of SMX by the biochar follows the pseudo-second-order kinetics model; the Langmuir model can describe the adsorption isotherm of SMX onto acid-modified biochar better, but adsorption process one the unmodified and alkali modified biochar fit better with the Freundlich model. The adsorption process of SMX by the biochar was endothermic and spontaneous. pH and the dosage of biochar added has a significant effect on the adsorption of SMX by the biochar. The adsorption process was jointly influenced by pore filling, hydrogen bonding, π-π EDA, and electrostatic interactions.
