Soil Remediation with Cross-Linked Amphiphilic Nano-Particles

项目负责人：Claude Cohen机构：康奈尔大学提案号：0086754本项目涉及使用新型交联两亲聚合物纳米颗粒去除污染土壤中的疏水有机污染物的研究。实验工作将针对聚合物合成、聚合物表征、两亲性聚合物网络在多孔介质中的命运和运输的实验室评估，以及它们在去除多核芳香烃（PAH）化合物方面的功效，这些化合物将被用作模型疏水有机污染物。通过在水包油悬浮液中交联液滴，可以在纳米尺度上制备聚合物网络。初步实验表明，高分子纳米颗粒在土壤修复中具有较表面活性剂更低的吸附和更大程度的去除多环芳烃的优点。

PI: Claude Cohen Institution: Cornell University Proposal Number: 0086754This project involves the study of the use of novel cross-linked amphophilic polymer nano-particles in the removal of hydrophobic organic pollutants from contaminated soil. The experimental effort will be directed toward polymer synthesis, polymer characterization, and laboratory evaluations of the fate and transport of amphiphilic polymer networks in porous media, and of their efficacy in the removal of polynuclear aromatic hydrocarbon (PAH) compounds that will be employed as model hydrophobic organic contaminants. Polymer networks can be prepared in nano-size scale by cross-linking droplets in an oil-in-water suspension. Preliminary experiments have demonstrated that polymer nano-particels have advantages over surfactants in soil remediation including low adsorption onto soil and greater extent of removal of PAHs.
