摘要
在这项研究中，合成了新的分子印迹聚合物颗粒(MIP)，利用自由基聚合从水溶液中提取Cu2+离子。以甲基丙烯酰胺-乙二醇二甲基丙烯酸酯(EGDMA)交联剂、甲基丙烯酰胺单体和ACV引发剂为原料，采用自由基聚合法制备了MIP。通过对不同交联剂在MIP生产中的比较，发现最佳的交联剂是EGDMA和没食子酸。用0.100 M HCl浸出去除模板离子。采用红外光谱(FTIR)、热重分析(TGA)和扫描电镜(SEM)对聚合物颗粒进行了表征。考察了交联剂、pH、时间、最大吸附量、吸附动力学和等温吸附等参数的影响。确定了最佳条件(pH = 8.0, t = 10 min, qm = 262.53 mg g−1)。Freundlich等温线和拟二级动力学模型对吸附数据拟合较好。该方法吸附量大，具有多层性，是一种简便、快速、安全的阳离子提取方法。用甲基丙烯酰胺-乙二醇二甲基丙烯酸酯(EGDMA)开发MIP的工业废水样品(伊朗Charmshahr)在含有化学性质相似的组分(如Co2+， Zn2+， Fe2)的基质中可以很好地测定Cu2+。
A rapid and sensitive method for separation of Cu2+ ions from industrial wastewater sample and water samples with methacrylamide-ethylene glycol dimethacrylate: A new synthesis of molecularly imprinted polymer
In this study, new molecularly imprinted polymer particles (MIP) were synthesised to extract Cu2+ ions from aqueous solutions using radical polymerisation. MIP was developed using the methacrylamide-ethylene glycol dimethacrylate (EGDMA) cross linking agent, methacrylamide monomer, and ACV initiator by the radical polymerisation method. A comparison of various cross linking agents in MIP production showed that the best cross linking agents are EGDMA and gallic acid. The template ions were removed by leaching with 0.100 M HCl. The polymer particles were characterised by FTIR spectroscopy, thermogravimetric analysis (TGA) and scanning electron microscopy (SEM). The effect of different parameters such as cross linkers, pH, time, maximum adsorption capacity, and kinetic and isotherm adsorption were investigated. The best conditions were determined (pH = 8.0, t = 10 min, and qm = 262.53 mg g−1). The adsorption data were best fitted by Freundlich isotherm and pseudo second order kinetic models, as well. Due to its high adsorption capacity and multi-layer behaviour, this method is an easy, fast and safe way to extract cations. Removal of Cu2+ in certified tap water and rain water was demonstrated and the industrial wastewater sample (Charmshahr, Iran) with which the MIP was developed using Methacrylamide- Ethylene Glycol Dimethacrylate (EGDMA) was good enough for Cu2+ determination in matrices containing components with similar chemical property such as Co2+, Zn2+, Fe2.
期刊介绍：
Electrical and electronic engineers have a long and illustrious history of contributing new theories and technologies to the biomedical sciences. This includes the cable theory for understanding the transmission of electrical signals in nerve axons and muscle fibres; dielectric techniques that advanced the understanding of cell membrane structures and membrane ion channels; electron and atomic force microscopy for investigating cells at the molecular level.
Other engineering disciplines, along with contributions from the biological, chemical, materials and physical sciences, continue to provide groundbreaking contributions to this subject at the molecular and submolecular level. Our subject now extends from single molecule measurements using scanning probe techniques, through to interactions between cells and microstructures, micro- and nano-fluidics, and aspects of lab-on-chip technologies. The primary aim of IET Nanobiotechnology is to provide a vital resource for academic and industrial researchers operating in this exciting cross-disciplinary activity. We can only achieve this by publishing cutting edge research papers and expert review articles from the international engineering and scientific community. To attract such contributions we will exercise a commitment to our authors by ensuring that their manuscripts receive rapid constructive peer opinions and feedback across interdisciplinary boundaries.
IET Nanobiotechnology covers all aspects of research and emerging technologies including, but not limited to:
Fundamental theories and concepts applied to biomedical-related devices and methods at the micro- and nano-scale (including methods that employ electrokinetic, electrohydrodynamic, and optical trapping techniques)
Micromachining and microfabrication tools and techniques applied to the top-down approach to nanobiotechnology
Nanomachining and nanofabrication tools and techniques directed towards biomedical and biotechnological applications (e.g. applications of atomic force microscopy, scanning probe microscopy and related tools)
Colloid chemistry applied to nanobiotechnology (e.g. cosmetics, suntan lotions, bio-active nanoparticles)
Biosynthesis (also known as green synthesis) of nanoparticles; to be considered for publication, research papers in this area must be directed principally towards biomedical research and especially if they encompass in vivo models or proofs of concept. We welcome papers that are application-orientated or offer new concepts of substantial biomedical importance
Techniques for probing cell physiology, cell adhesion sites and cell-cell communication
Molecular self-assembly, including concepts of supramolecular chemistry, molecular recognition, and DNA nanotechnology
