Liquid Chromatography Method

By solid - phase extraction high performance liquid chromatography determination of nonylphenol, Octylphenol in aquatic product residues, to establish more accurate, fast, effective detection method. Sample is 3 trichloroacetic acid solution after extraction, using anion exchange solid phase extraction column purification by reversed phase high performance liquid chromatography method for determination. Column is Shim-pack VP-ODS 250mm x4.6mm, detection wavelength is225 nm, mobile phase of methanol - water ( volume ratio of 75:25), flow rate is 0.8 mL/min, injection volume is 20 ìL. Octylphenol, nonylphenol respectively in 0.14¡«97.63 ìg/mL ( R=0.9995),0.02¡«51.04 ì g/mL ( R=0.9997) concentration and peak area show a good linear relationship, octylphenol nonylphenol and the recovery is 87.9%¡«93.8%, relative standard deviation is 1.4%¡«3.8%. Solid - phase extraction high performance liquid chromatography method for determination of aquatic product of octylphenol and nonylphenol residue is accurate, rapid, high sensitivity, suitable for aquatic products of octylphenol nonylphenol and detection.
