| Abstract: | An analytical method was presented for determination of 11 phenols in waste water samples by high-performance liquid chromatography (HPLC) with solid-phase extraction (SPE) by Supelclean ENVI-Chrom P tubes. The extracting conditions of SPE and instrument analysis condition of HPLC were discussed. This established method had the advantages of excellent separation and purification efficiency, the corresponding detection limits of this method were 2×10-3-2×10-2 mg/L. The relative standard deviations of this analytical method for six parallel determinations were 2.7%-16.4%. Except a lower recovery of 2, 4-dinitrophenol, the recoveries of the rest phenols all ranged from 61.4% to 115.8%. |
