Abstract:

This Final Report begins with a description of two catalysts and one microemulsion that are effective decontamination systems for mustard and nerve agent simulants. It then describes new ester-modified surfactants synthesized in the hopes that they would provide enhanced solublilization power. In the process, a comparison was made between contiguous and segmented hydrophobicity, the first such comparison of its kind. Surfactants were found to differ in their cmc, foaming, area of occupancy at the airwater interface, and solid-adsorption and solublization power depending on the location of the ester groups within the chains. Finally, the first cryo-etch-high resolution scanning electron microscopy study of aqueous saline was carried out to learn how salt is excluded from frozen water.
