Abstract

GAS CHROMATOGRAPHY (GC) IS A POPULAR TECHNIQUE FOR THE ANALYSIS OF PHENOL COMPOUNDS.HOWEVER, BECAUSE OF THEIR HIGH POLARITY, THESE ANALYTES TEND TO GIVE BROAD, TAILED PEAKS, AND THESE EFFECTS INCREASE AS THE CHROMATOGRAPHIC COLUMN AGES. TO AVOID THESE DRAWBACK, SEVERAL DERIVATIZATION REACTIONS HAVE BEEN PROPOSED TO TRANSFORM PHENOLS IN LESS POLAR COMPOUNDS, WITH BETTER CHROMATOGRAPHIC CHARACTERISTICS. PHENOL ACETYLATION WITH ACETIC ANHYDRIDE IN PRESENCE OF CARBONATE OR HYDROGENCARBONATE, IS ONE OF THE MOST COMMON DERIVATIZATION PROCEDURES. REACTION CAN BE PERFORMED IN AQUEOUS SAMPLES IN A FEW MINUTES WITH HIGH EFFICIENCY. PHENYL ACETATE WAS EXTRACTED BY SEVERAL METHODS [1-3].IN THIS RESEARCH, WE COMPARED SOLID-PHASE EXTRACTION (SPE) WITH CONVENTIONAL REVERSED PHASE ADSORBENT SUCH AS C18 AND LIQUID-LIQUID EXTRACTION (LLE) WITH N-HEXAN. ACCORDING TO RESULTS, EXTRACTION EFFICIENCY IN SPE PROCEDURE IS LOWER THAN LLE AND TIME CONSUMING. THE EXTRACTED SAMPLES WAS ANALYZED BY GAS CHROMATOGRAPHY WITH MASS SPECTROMETRY DETECTION (GC–MS).EXPERIMENTS, WERE PERFORMED TO CHECK THE EFFECT OF SAMPLE CONCENTRATION AND DETERMINATION OF EFFICIENCY OF RECOVERY, ULTRAPURE WATER WAS SPIKED BY THREE CONCENTRATION LEVELS OF PHENOL.THE MEAN RECOVERY AND RELATIVE STANDARD DEVIATION IS 85±7.8%. CALIBRATION CURVE WAS LINEAR IN THE CONCENTRATION RANGE OF 10 NG ML-1 TO 2 MG ML-1 IN THE ORIGINAL SOLUTION AND CORRELATION COEFFICIENT IS 0.9998. THE DEVELOPED METHOD HAS BEEN USED TO MONITOR PHENOL CONTAMINATION IN RIVER WATER SAMPLES COLLECTED FROM ZAYANDEROUD RIVER IN ISFAHAN PROVINCE, IRAN.
