摘要/Abstract

摘要：

以KAl(SO₄)₂和尿素为前驱体,通过微波水热法于180 ℃反应20 min,经600 ℃焙烧2 h制得分级多孔γ-Al₂O₃空心微球.所制备的样品被用于吸附典型有机染料刚果红(CR)溶液.结果表明,制备的γ-Al₂O₃空心微球直径为0.8-1.0 μm,厚度约为200 nm.此γ-Al₂O₃空心微球具有高的比表面积(243 m²·g^-1)和分级大孔-中孔结构,此结构非常有利于液相过程中的质量传递.微波水热法制备的γ-Al₂O₃空心微球比水热法制备的γ-Al₂O₃和商用的γ-Al₂O₃样品显示出更快和更强的吸附性能.此样品的吸附数据很好地符合假二级速率方程和Langmuir吸附理论模型.从Langmuir吸附理论模型计算得到微波水热法制备的γ-Al₂O₃空心微球的最大吸附量(q_max) 25 ℃时高达515.4 mg·g^-1.由于具有分等级结构、高比表面积、大的孔容和吸附能力,微波水热法制备的γ-Al₂O₃空心微球样品有望成为一种具有很好应用潜力的环境吸附剂.

Abstract:

Hierarchical nanostructured γ-Al₂O₃ hollow microspheres were synthesized from KAl(SO₄)₂ and urea precursors by the microwave-assisted hydrothermal (MAH) method at 180 ℃ for 20 min followed by calcination at 600 ℃ for 2 h. The as-prepared sample was used to remove the organic dye Congo red (CR) from aqueous solution. The results showed that the obtained γ-Al₂O₃ hollow microspheres are about 0.8-1.0 μm in diameter with a shell thickness of approximately 200 nm. The γ-Al₂O₃ hollow microspheres have a high surface area of 243 m²·g^-1 and a hierarchical meso-macroporous structure, which is beneficial for mass transfer in liquid processes. Therefore, the prepared γ-Al₂O₃ hollow microspheres exhibit faster adsorption and enhanced adsorption performance for CR than particles prepared by the hydrothermal method and commercial γ-Al₂O₃. The adsorption kinetic data follow the pseudo-second-order equation and the equilibrium data fit well to the Langmuir model. The maximum adsorption capacity (q_max) of the obtained γ-Al₂O₃ hollow microspheres calculated by the Langmuir model is up to 515.4 mg·g^-1 at 25 ℃. The γ-Al₂O₃ hollow microspheres prepared by the microwave-assisted hydrotherm method show promise as an adsorbent for environmental applications due to their hierarchical porous structure, high surface area, large pore volume, and adsorption capacity.
