Abstract

A method for the determination of Abate in water has been modified to determine the 4,4'-thiodiphenol in human and rat urine. The method involves acid hydrolysis of conjugated residues, extraction, silylation, cleanup, and gas chromatography using the flame photometric detector equipped with a sulfur filter. The method can be used for the determination of the other Abate metabolites, 4,4'-sulfinyldiphenol and 4,4'-sulfonyldiphenol. The recovery of the 4,4'-thiodiphenol from fortified human urine was 75-87%. The minimum detectable amount is 0.02 ppm.
