“…Phenolic compounds are usually determined by reversed-phase liquid chromatography (RPLC) using different detection systems such as UV (diode-array detection), 1-4 electrochemical 5,6 or fluorescence. 7,8 On the other hand, pesticides are usually determined by GC or RPLC, with a variety of detection systems. [9][10][11][12][13] Unfortunately, the use of these detectors usually does not enable the detection limits required by legislation to be reached and hence it is necessary for the sample to be enriched prior to the chromatographic analysis.…”

A comparative study of a chemically modified polymeric resin which has a benzoyl group and several commercial sorbents, such as PLRP-S, Envi-chrom P and LIChrolut EN, for the solid-phase extraction of various phenolic compounds and pesticides was carried out. Selectivity and breakthrough volumes for these compounds with different sorbents were studied by coupling an on-line solid-phase extraction system with a modified liquid chromatograph equipped with a UV detector. After determining the chromatographic conditions, linearity range and detection limits, the method was applied to the determination of these compounds in drinking and surface water. For 25 ml of sample, the recovery was > 70% for all the compounds, except for 4-nitrophenol (62%), and detection limits were between 0.2 and 0.8 microgram I-1.

Phenolic compounds are widely distributed in our ecosystems. In addition to naturally occurring phenols, the majority of toxic phenolic substances are released into the environment by industry and agriculture. As the manufacture and use of phenols requires qualitative and quantitative control, a wide variety of methods have been developed to determine phenolic compounds. In addition to coarse screening to rapidly obtain a general overview, many highly specialized techniques exist that are geared to individual analysis problems. The range of available methods extends from steam distillation and classic liquid–liquid extraction (LLE) as sample preparation combined with photometric or ultraviolet (UV) detection, to more sophisticated techniques such as liquid–solid extraction (LSE) including solid‐phase extraction (SPE) and solid‐phase microextraction (SPME) coupled to gas chromatography/mass spectrometry (GC/MS) and high‐performance liquid chromatography/mass spectrometry (HPLC/MS). This article describes the most suitable methods, taking account of special factors such as substance class, chemical properties, concentration range and accompanying matrices. Some new trends in phenol determination are also discussed in comparison with the established methods. The basic factors governing the selection of suitable analysis methods are also covered.

“…Many analytical methods, including capillary electrophoresis [10,11], high-performance liquid chromatography (HPLC) [12] and gas chromatography [1] are available for the determination of CPs in water samples. Gas chromatography (GC), usually after derivatization, with flame-ionization detection (FID) [13,14], electron-capture detection (ECD) [15], mass spectrometric detection (MS) or microwave-induced plasma atomic emission spectrometry (MIP-AES) [16][17][18][19] is a common tool for the determination of phenols because of its high separation power and low limits of quantification.…”

a b s t r a c tSolid-phase extraction (SPE) followed by derivatization and gas chromatography-atomic emission detection (GC-AED) was evaluated for the determination of five chlorophenols (CPs) in water samples. The derivatization was based on the esterification of phenolic compounds with ferrocenecarboxylic acid. The determination of the derivatized phenols was performed by GC-AED in the iron selective detection mode at 302 nm. The described method was tested on spiked water samples.The overall method gave detection limits of 1.6-3.7 ng L −1 and recoveries of 90.9-104.5% for the examined mono-to trichlorophenols in 10 mL water samples. The CPs extracted from a 10 mL water sample with SPE were concentrated into 100 L of organic solvent, a preconcentration factor of 100. The method was applied to lake and tap water samples, and CP contents between 6 and 51 ng L −1 in lake water and between below the detection limit and 8 ng L −1 in tap water were found for different CPs. The method is quick, simple and gives excellent recoveries, limits of detection and standard deviations.
