摘要 以异丙醇铝(AIP)为前驱体,聚乙烯吡咯烷酮(PVP)为聚合物模板,结合溶胶-凝胶、静电纺丝和高温煅烧的方法制备了Al2O3纳米纤维毡,研究了煅烧温度对Al2O3纤维毡的形貌、孔隙结构和吸附脱色性能的影响,并探讨了其吸附脱色机理和循环再生性能。结果表明,制得的Al2O3纤维毡具有较好的结构形貌和均匀的纤维直径,经800 ℃煅烧后的Al2O3纤维毡的BET比表面积约为82.7 m2/g,对活性红X-3B和酸性安诺赛特黄TB染液的吸附率分别高达72%和93%,这归因于二者之间的静电作用,并且该Al2O3纤维毡具有良好的循环稳定性和可靠性。因此,电纺Al2O3纤维毡在染料废水的吸附脱色方面具有潜在的应用前景。

Abstract: Electrospun alumina (Al2O3) nanofibrous mats were fabricated by combing sol-gel, electrospinning and high temperature calcination techniques, based upon aluminum isopropoxide (AIP) as precursor and polyvinylpyrrolidone (PVP) as polymer template. The effects of calcination temperature on structural morphology, porous structure and decolorization property of Al2O3 mats were investigated. The decolorization mechanism and recycling/regeneration property of Al2O3 mats were also discussed. The results showed that the fabricated Al2O3 mats possessed good structure and morphologies with homogeneous fiber diameters. The Al2O3 mats calcined at 800 ℃ had the BET specific surface area of 82.7 m2/g, and demonstrated excellent adsorption rate on Reactive Red X-3B and Acid ANOSET© Yellow TB and reached about 72% and 93%, respectively. This might be due to electrostatic interactions between Al2O3 mats and dyes. The Al2O3 mats also exhibited good cycle stability and re-liability. This study suggests that the fabricated Al2O3 mats have potential applications for adsorption and decoloration on dye wastewater field.
