Abstract : This study tests the hypothesis that the organic molecules, 2,9-dimethyl-1,4,7-diphenyl-1,10-phenanthroline (Bathocuproine (BCP)) and 2,9-dimethyl-4,7-diphenyl-1,10-phenanthrolinedisulfonic acid (Bathocuproinedisulfonic acid (BCS)) are reliable chemicals to use in developing a standard analysis procedure (BCS) and for testing an optical fiber sensor (BCP) capable of measuring copper(I) in seawater. Results show the BCS chemical provides a quick and relatively easy way to determine the concentration of copper(I) in marine and estuarine waters. Bathocuproine (BCP), once attached to optical fibers, allows for a rapid electronic measurement to quickly detect the amount and pattern of copper(I) released into the marine environment.
