Abstract : The overall goal of this research is to develop pH responsive phase transfer polymers capable of removal of water borne contaminants. The phase transfer efficiency of these 'smart' systems is enhanced by maximum interfacial surface area contact between microheterogeneous domains and foulant species. Therefore, this chemistry is amenable for use in microphase separated, polymeric surfactant solutions (liquid membranes), supported hydrogel membranes, grafted and interpenetrating polymer networks, and nanocomposites. For the ESS program, hydrophobic organic and amphiphilic compounds in confined grey water are our targets for remediation. Major project objectives involve: preparation of precisely tailored synthetic and biosynthetic polymers with domain structures responsive to changes in pH, electrolyte, temperature and shear; study of the extent of domain formation and reversibility utiliziing photophysical techniques; examination of the extent and nature of transfer, sequestration, and phase stability with model grey water contaminants; and optimization of the efficiency of polymer and model pollutant separation and recovery. An often overlooked but important goal of this work is the interdisciplinary training and education of young scientists in this vital environmental area. pg12. JMD
