摘要：

A gas chromatographic method for the determination of residues of 2,4,5-trichlorophenoxyacetic acid and its propylene glycol butyl ether esters in tissues and fluids is described. Both compounds were converted to the methyl ester of 2,4,5-T and analyzed by microcoulometric gas chromatography using a column of 15% Dow 710 on Chromport XXX. Average recoveries of 2,4,5-T added to fat, lean tissue, urine, and blood at levels from 0.05 p.p.m. to 20 p.p.m. were 89.3, 89.6, 93.0, and 93.6%, respectively. Corrected recovery of unmetabolized ester added to fat, lean tissue, urine, and blood at levels from 0.5 p.p.m. to 20 p.p.m. averaged 77.9, 70.5, 94.2 and 92.5%, respectively. © 1969, American Chemical Society.
