TI  - Determination of substituted diphenylamines in environmental samples.
PG  - 7945-7954
AB  - Owing to their stability at high temperature, low biodegradation, low water 
      solubility, and low vapor pressure, substituted diphenylamines are used as 
      antioxidants in rubber, foamed polymers, and as high-temperature functional 
      fluids (e.g., lubricants, gear oils, and hydraulic fluids). There are few 
      existing environmental measurements of these substances in any environmental 
      medium. In this study, a method was developed for the determination of 10 
      substituted diphenylamines in wastewater, biosolids, and sediments using gas 
      chromatography-tandem mass spectrometry (GC-MS/MS). The substituted 
      diphenylamines that were measured were two styrenated diphenylamines isomers, 
      three di-styrenated diphenylamine isomers, tert-butyl-diphenylamine, 
      tert-octyl-diphenylamine, di-tert-butyl-diphenylamine, 
      tert-butyl/tert-octyl-diphenylamine, and di-tert-octyl-diphenylamine. The 
      instrument limits of detection (LODs) and limits of quantitation (LOQs) were 
      0.02-0.1 and 0.06-0.3 ng mL(-1), respectively. Target compounds were spiked into 
      sediment, effluent water, influent water, and biosolids at the 100- and 1000-ng 
      levels (N = 6). Analyte recoveries ranged from 71.5 to 117 % with relative 
      standard deviations (RSDs) of 2.12-12.4 %. The method was applied to the analysis 
      of influent, effluent, and biosolid samples; the sum of substituted 
      diphenylamines were 48.1-713, 1.04-28.5 ngL(-1), and 85.3-1184 ngg(-1)dw (median: 
      71.0, 7.30 ngL(-1), and 402 ngg(-1)dw), respectively. Nine sediment samples 
      collected in Ontario, Canada contained concentrations of the sum of substituted 
      diphenylamines ranging from 1.55 to 897 ngg(-1)dw.
