Surfactant Selection For Use in Enhanced Remediation of Petroleum contaminated Ground Water: Surfactant Enhanced Subsurface Flushing and Micellar-Enhanced Ultrafiltration

这一奖项旨在支持一项概念研究，该概念旨在提高从被地下储罐泄漏污染的土壤中提取高碳含量石油碳氢化合物的速度。研究人员计划评估阴离子表面活性剂，由于其化学结构，阴离子表面活性剂对目标碳氢化合物具有增强的亲和力，并将其与阳离子和非离子表面活性剂在这方面的性能进行比较。研究人员计划使用胶束增强超滤技术对表面活性剂进行评估，这是一种基于表面活性剂的分离工艺，用于处理经过污染土壤的洗涤水。该工艺与适当的阴离子表面活性剂结合使用，有可能提供表面活性剂的回收，以便在土壤净化过程中重复使用。本提案是根据NSF项目公告88-99，研究启动奖而提交的。研究结果有望改善化学修复系统的工程设计，这些系统用于从被储罐泄漏的石油烃污染的土壤中去除石油烃。

This is an award to support research on a concept for improving the rate at which petroleum hydrocarbons with a high-carbon content, can be removed from soil that has been contaminated by leakage from underground storage tanks. The investigator plans on evaluating anionic surfactants that have an enhanced affinity for the target hydrocarbons because of their chemical structure, and comparing their performance in this respect with cationic and nonionic surfactants. The investigator plans to includes the evaluation of surfactants with the use of micellar-enhanced ultrafiltration, a surfactant-based separation process for treatment of the wash water after it has been circulated through the contaminated soil. This process in combination with the appropriate anionic surfactant has the potential of providing for recovery of the surfactant for reuse in the soil-decontamination process. This proposal was submitted in response to Program Announcement NSF 88-99, Research Initiation Awards. Results are expected to improve the engineering design of chemical remediation systems that are used to remove petroleum hydrocarbons from soil that has been contaminated by leakage of petroleum hydrocarbons from storage tanks.
