Abstract

Total phenolic compound values were determined in samples of river water by means of the Folin-Ciocalteu colorimetric method, while HPLC with UV detection was used to identify individual phenols. Preconcentration was needed in all cases to meet the required detection limits. Given the absorption coefficients of the components, the error incurred when a curve calibrated against phenol only is used to evaluate a mixture was calculated.
