A lot of progress has been made on the field of nanoporous polymers during the last few years. However, most of the systems still need to prove their benefit compared to classic nanoporous systems, such as activated carbon. One possibility would be to make use of the well-defined surface chemistry in adsorption applications. We propose the synthesis and characterisation of mesoporous polymers, i.e. polymers having pore sizes between 2 and 50 nm. The synthesis shall be designed in a way that allows a control of the final morphology of the materials, e.g. by using emulsion polycondensation or electrospinning. The formation of microparticles and membranes is envisaged. That way, the polymers should be directly useful for sorption purposes in water purification applications. The ad- or absorption of heavy metal ions and oxyanions (e.g. arsenates) is within the focus of the project. The underlying basics of the adsorption mechnanisms shall be investigated and dynamic separation protocols shall be developed.

近年来，纳米多孔聚合物的研究取得了很大的进展。然而，大多数系统仍然需要证明其与经典纳米多孔系统（如活性炭）相比的优势。一种可能性是在吸附应用中利用明确定义的表面化学。我们提出了介孔聚合物的合成和表征，即具有2和50 nm之间的孔径的聚合物。合成应设计成允许控制材料的最终形态，例如通过使用乳液缩聚或静电纺丝。设想形成微粒和膜。这样，聚合物应该直接用于水净化应用中的吸附目的。重金属离子和含氧阴离子（如砷酸盐）的吸附或吸收是该项目的重点。应研究吸附机理的基本原理，并制定动态分离方案。
