Title Automated determination of total phenol in urine
Bibliographic information June 1972, Vol.33, No.6, p.378-381. Illus. 5 ref.
Abstract A fully automated method has been developed to determine total phenol in urine. The reagents include a buffer solution, sulphuric acid, 4-aminoantipyrine and an oxidant. The analytical procedure involves hydrolysis of conjugated phenols and steam distillation, followed by colorimetric phenol determination in the distillate. Urine samples (1-2mL) are run sequentially at the rate of 10 per hour; the precision obtained is 1.6ppm per litre. The method could be used routinely to assess benzene exposure.
