ABSTRACT
Murray et al [1] have described a gas chromatographicmethod for the determination in water of triarylphosphate esters (1mol S-140, tricresyl phosphate, cresol phosphate). These substances are used commercially as lubricant oil and plastic additives, hydraulic fluids and plasticisers. The method involves extraction from the samples, hydrolysis andmeasurement of the individual phenols by gas chromatography as the trimethylsilyl derivatives. The lower detection limit was about 3 ppm.
