Abstract:
An improved method for the determination of urinary phenol by the traditional precolumn hydrolysis technique is described. Following acid hydrolysis and diethylether extraction, phenol is separated from other urinary components within 3 minutes using the proposed capillary GC method. Analytical recovery was over 95%. The within-run CV was less than 2% and the day-to-day variation was less than 8%.
