Method for the identification and determination of dibromoacetic acid (DBAA) in a chlorinated seawater have been studied. DBAA in a chlorinated seawater was concentrated by solvent extraction technique using diethyl ether followed by the methyl ester derivatization. The solution obtained was analyzed by GC/MS in electron impact ionization mode. The mass spectrum obtained from a chlorinated seawater was similar to that of a authentic compound of DBAA.
For the routine method of determining DBAA in chlorinated seawater, an electron capture detector gas chromatography preceded by the solvent extraction technique was applied to the analysis of chlorinated seawater samples. Results showed that DBAA was detected in the chlorinated seawater used in plants and a swimming pool. DBAA concentration in chlorinated seawater samples used in plants was proportional to that of bromoform, and the ratio of DBAA to bromoform concentration was calculated about 20%.
