生物模板法制备离子印迹磁性微马达及污水中Pb2+动态去除的研究

摘要/Abstract

摘要： 离子印迹材料是一种传统的选择性去除离子的材料,但吸附能力低、成本高等缺点限制了其大规模实际应用。探索一种高吸附容量和低成本的新型材料来捕获污水中的Pb²⁺是非常必要的。本文以自然界中的荷花花粉为模板,通过水热、浸渍煅烧、光照还原和离子印迹法,成功制备了一种新型Pb²⁺印迹Janus磁性微马达复合材料。结果表明,非对称球形微马达对污水中Pb²⁺具有较高的选择性吸附能力,吸附最大值可达67.12 mg/g。Pb²⁺的吸附动力学和热力学过程符合伪二级动力学模型和Langmuir模型。此外,制备的样品具有良好的磁性,可进行方向控制和循环利用。本文为高效、高选择性去除污水中的Pb²⁺提供了一种有效的策略。

Abstract: Ion Imprinted polymer (IIP) is a traditional material for selective removal of ions, but its low adsorption capacity and high cost limit widely practical application. Exploring a novel material with high adsorption capacity and low cost to capture Pb²⁺ is necessary but very challenging. Herein, a novel Pb²⁺ imprinted Janus magnetic micromotor was successfully fabricated by hydrothermal, impregnation calcination, photoreduction and ion imprinted method using naturally available and low-cost lotus pollen as biological template. Theresults show that the asymmetric spherical micromotor was able to have a highly selective adsorption ability to Pb²⁺ in sewage and the maximum adsorption value reaches 67.12 mg/g. The adsorption process of the kinetics and thermodynamics of Pb²⁺ follow well in line with pseudo-second-order kinetic model and Langmuir isotherm model. In addition, the prepared samples not only have good magnetism for direction control and recycling, but also exhibite excellent reusability in practical application. This work provides an effective strategy for effcient and selective removal of Pb²⁺ from sewage.
