  • 摘要: 以酸热、有机改性凹凸棒和聚醚砜为原料，利用液-液分离技术制备了聚醚砜/改性凹凸棒毫米级杂化微球。利用扫描电镜和比表面仪分析所制杂化微球表观特征。实验探讨了改性凹凸棒掺杂比和溶液pH对杂化微球吸附双酚A效果的影响，并深入研究了吸附动力学和热力学原理。实验结果表明：杂化微球对双酚A的吸附性能受pH影响较小；相比纯聚醚砜微球，掺杂后的杂化微球对双酚A吸附量从1.97 μmol·g-1提升到11.80 μmol·g-1；吸附过程符合准二级动力学模型和Langmuir模型。根据Langmuir模型计算可知，25 ℃时杂化微球最大吸附量为116.28 μmol·g-1。5次乙醇再生后，杂化微球对双酚A的去除效果依然保持在95%以上。杂化微球作为吸附剂在水处理中具有潜在应用价值。
    Abstract: By liquid-liquid separation technique, polyethersulphone/modified attapulgite hybrid microspheres were prepared with acid，heat and organic modified attapulgite and polyethersulphone. The apparent characteristics of hybrid microspheres were analyzed by scanning electron microscope and BET surface analyzer. The effects of modified attapulgite dosage and solution pH on adsorption of bisphenol A on the hybrid microspheres were investigated. Kinetic and thermodynamic principles were applied to describe adsorption process. The results show that adsorption properties of hybrid microspheres were less affected by pH. Compared of polyethersulphone microspheres, the adsorption capacity of hybrid microspheres for bisphenol A increased from 1.97 μmol·g-1 to 11.80 μmol·g-1. Adsorption process fits with pseudo second-order kinetic model and Langmuir model. According to Langmuir model, maximum adsorption capacity of hybrid microspheres is 116.28 mol·g-1 at 25 ℃. After the fifth regeneration with ethanol, the removal efficiency of bisphenol A kept above 95%. Hybrid microspheres have potential applications in water treatment as novel adsorbent.
