摘要
水污染是全世界关注的环境问题。去除水中的污染物是一个非常重要的研究领域。苯胺是一种极具毒性的有机化工原料。因此,去除污水中的苯胺成为很多国家的水治理重点项目。开发环境友好的,廉价的,操作简单的,可用于纯化苯胺污染水体的材料成为了一个重要的研究方向。相选择性凝胶因子是一种可以选择性凝胶化油水混合物中油相的小分子凝胶因子,近年来利用此类凝胶因子对水体纯化和石油泄漏回收的研究十分活跃。最近我们合成了一类新的相选择性凝胶因子。研究发现这种凝胶因子可以从苯胺和水的混合液中选择性的凝胶苯胺。并且只需对混合液进行机械震荡或搅拌就可以完成选择性凝胶苯胺的过程。这一发现提高了此材料的实际应用价值。
Water pollution is an environmental issue of world-wide focus. Removal of contaminants from water is a very important research area. Aniline is an important material in organic industry, which is very poisonous. The waste water containing aniline has become the key treatment target of each country. The development of eco-friend, easy-to-operate, low-cost, easy recovered material for the purification of aniline-containing water become in great demand. Phase-selective gelators(PSGs) that prefer to gelate one solvent rather than gel the other in a given biphasic mixture, have been actively studied on water purification and the oil spill recovery from water. In this work, a mandelic acid-based PSG has been synthesized. It was found that only simple mechanical shaking could realize the homogeneous dispersal of the gelators in organic phase and further facilitate to complete the gel formation in water, which demonstrated its real-life application potential.
