Materials for Selective and Sustainable HydroCarbon Removal from Water

用于选择性和可持续去除水中碳氢化合物的材料

基本信息

项目摘要

We propose to develop and to investigate a new efficient class of non-toxic materials for waste water treatment from hydrocarbons (HCs). Based on the proposed design, these materials will be able adsorb very efficiently most kind of hydrocarbons with adjustable preference related to the chemical composition of the HC contaminants (e.g. alkanes, aromatic-, oxo- or sulfur functionalized or halogenated hydrocarbons). This key feature will be realized by special functional molecules, which form a self-assembled monolayer on the surface of magnetic nanoparticles. The adsorption of HCs is reversible and dedicated to non-covalent interactions (van-der Waals, H-bonding, dipole, -interaction) provided by the molecular design of the SAM molecules. Due to the magnetic core, the adsorbed HCs become removable from water by simply applying an external magnetic field. These properties potentially enable a closed-loop process with the unique advantage of full recovery of the HCs and the nanoparticles. We do not expect only results of enormous practical (economical, environmental) relevance, rather than a new insight in to core-shell nanoparticles with defined mixed shells (binary, ternary and quaternary composition). Our system provides a perfect test vehicle to study even orthogonal functionality of SAM molecules on one NP-surface as interaction surface to complex mixtures chemical compounds in aqueous matrix. We hope to generate new design strategies for inverted micelle systems which can be composed of several different molecules in a reliable way.
我们建议开发和研究一种新的高效无毒材料,用于碳氢化合物(HCs)的废水处理。基于所提出的设计,这些材料将能够非常有效地吸附大多数种类的烃,其中具有与HC污染物的化学组成相关的可调节的偏好(例如,烷烃、芳族、氧代或硫官能化或卤代烃)。这一关键特征将通过特殊的功能分子在磁性纳米颗粒表面形成自组装单层来实现。HC的吸附是可逆的,并且致力于SAM分子的分子设计所提供的非共价相互作用(范德华力、H-键合、偶极、双极相互作用)。由于磁芯,吸附的HC变得可通过简单地施加外部磁场从水中去除。这些特性可能使闭环过程具有完全回收HC和纳米颗粒的独特优势。我们并不期望只有巨大的实际(经济,环境)相关性的结果,而不是一个新的见解,以核壳纳米粒子与定义的混合壳(二元,三元和四元组成)。我们的系统提供了一个完美的测试车辆,研究甚至正交功能的SAM分子在一个NP-表面作为相互作用表面复杂的混合物化合物在水基质中。我们希望能产生新的设计策略,可以组成的几个不同的分子在一个可靠的方式反胶束系统。
