项目摘要

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.

这一奖项是为了支持一项概念的研究，该概念旨在提高从被地下储罐泄漏污染的土壤中去除高碳含量石油碳氢化合物的速度。研究人员计划评估由于其化学结构而对目标碳氢化合物具有更强亲和力的阴离子表面活性剂，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强化超滤对表面活性剂进行评估，这是一种基于表面活性剂的分离过程，用于在洗涤水循环通过受污染的土壤后进行处理。这一过程与适当的阴离子表面活性剂相结合，有可能回收表面活性剂，以便在土壤去污过程中重复使用。这项提案是为了响应NSF 88-99“研究启动奖”项目公告而提交的。预计结果将改进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碳氢化合物污染的土壤中清除石油碳氢化合物。
