摘要

摘要: 以废瓦楞纸为原料,通过简便的"破碎-FeCl₃/无水乙醇浸渍-常压干燥-炭化"工艺制备了一种新颖的磁性生物炭气凝胶(BCA_Fe-600);对材料的微观形貌、表面元素组成、晶相结构、比表面积、表面官能团、机械强度、磁性、亲水性、Zeta电位进行了分析和比较;研究了BCA_Fe-600对水中亚甲基蓝(MB)的吸附等温线,并将其用作一种可磁回收的漂浮型吸附材料,模拟了其对MB污染水体的净化过程,明确了吸附动力学特征。结果表明:BCA_Fe-600由无序交错的条带状炭纤维构成,具有良好的亲水性,其主要晶相组成为无定形碳、磁赤铁矿(γ-Fe₂O₃)和方解石(CaCO₃);FeCl₃可以促进废瓦楞纸在热解炭化过程中的孔隙发育以及最终材料的机械强度,其最终分解产物γ-Fe₂O₃赋予材料良好的磁性,因此,BCA_Fe-600的比表面积和饱和磁化量达到205 m²/g和7.62 emu/g,且可耐受自重450倍的压力。BCA_Fe-600对水中MB的吸附过程可用 Langmuir 模型描述,其最大单分子层吸附量为 35.6 mg/g;BCA_Fe-600可漂浮于MB溶液中,在静置条件下对MB也具有显著的吸附去除作用,其吸附动力学符合拟二级动力学模型。

Abstract: A novel magnetic biochar aerogel (BCA_Fe-600) was prepared from waste corrugated paper via crushing followed by impregnation with FeCl₃/ethanol solution and carbonization. The materials’ morphology, elemental composition, crystal structure, surface area, surface functional groups, mechanical property, magnetic property, hydrophilicity, and Zeta potential were analyzed and compared. The adsorption isotherm of BCA_Fe-600 for methylene blue was studied, and BCA_Fe-600 was used as a magnetic separable and floatable adsorbent for the purification of the simulated methylene blue polluted natural water. The results showed that the hydrophilic BCA_Fe-600 was composed of criss-crossed ribbon-like carbon fibers, and the main chemical constituents of BCA_Fe-600 were amorphous carbon, maghemite, and calcite. The presence of FeCl₃ benefited the evolution of porous structure and the mechanical strength of BCA_Fe-600, and maghemite derived from FeCl₃ gave magnetism to BCA_Fe-600, possessing a BET surface area of 205 m²/g and a saturated magnetization value of 7.62 emu/g. The Langmuir model was applicable for fitting the adsorption isotherm data for methylene blue with a maximum adsorption capacity of 35.6 mg/g, and the adsorption kinetics of methylene blue on the floatable BCA_Fe-600 complied with pseudo-second-order kinetics model.
