Direct Optical Research Methods in the Analytics of Phenol

摘要

The possibility of determining phenol in water by direct optical methods without the use of wet chemistry and concentration methods is considered. The bounds for determining the concentration of phenol in water from the absorption and luminescence spectra are estimated. As a reason limiting the use of the direct luminescent method for determining phenol, the influence of Raman effect of the solvent is considered, which becomes comparable with the luminescent signal even at phenol concentrations in water at a level of 10 mu g/L, despite the fact that the sensitivity of the method is sufficient to determine concentrations that are 50 times less.
