Student: Ji Yeam Ji is currently investigating the hydrolytic stability of telomer-based monomers as a function of pH and temperature. He will be testing various chemical linkages tested including ester, ether and urethane linkages. The kinetics and mechanism of hydrolysis as well as identification of products will also be examined. The hydrolytic stability of these compounds is of importance as they may enter aquatic systems through various routes including urban run off, drainage, waste disposal and industrial effluent. Thus, these compounds may be subjected to hydrolytic reactions that may release fluorotelomer alcohols (FTOHs), compounds found to be precursors to perfluorocarboxylic acids (PFCA) such as perfluorooctanoic acid (PFOA). This study is critical in evaluating all potential sources of this emerging class of persistent organic pollutant (POP) in the environment.
