Abstract:

This report describes the development and application of techniques for the spectroscopic study of hazardous fuel compounds in soils. The objective is to obtain improved models of bulk pollutant transport through soils. Two approaches have been used for this study one consists of in-situ measurements of electronic and vibrational interactions via ultraviolet-visible spectroscopy and infrared spectroscopy, respectively the other incorporates analytical separation techniques to extract contaminants from soils and identify individual reaction products. Initially, montmorillonite clay has been chosen as a prototype soil sample because the structure of this clay is well characterized and spectroscopic results can be readily interpreted. Further simplification has been obtained by exposing the clay samples to individual fuel components rather than mixtures. An interpretation of one clayfuel system has been accomplished. The plan is to gradually increase the complexity of the samples until typical field conditions can be modeled.
