DETERMINATION OF PHENOLS IN WATER USING RAMAN-SPECTROSCOPY

The potential of Raman spectroscopy for quantitative analysis of phenols in water solution has been investigated. A group of six compounds - phenol, o-chlorophenol, 2,4-dichlorophenol, 2,4,6-trichlorophenol, 2-chloro-5-methylphenol and 2-chloro-4-nitrophenol - was studied with the use of the 514. 5, 488. 0, and 457. 9 nanometer lines of an argon ion laser. Attention was given to the effects of source intensity, optical alignment, and background fluctuations on quantitative results. It was found that the use of an internal standard with each measurement made a significant improvement in the accuracy and precision of results.
