Zhang X, Wu R: [Analysis of phenolic compounds in mineral water by high performance liquid chromatography (HPLC)]. Se Pu. 1998 Nov;16(6):530-1.
A high performance liquid chromatographic method for the simultaneous analysis of phenolic compounds, such as, phenol, m-cresol, bisphenol A, bisphenol F, 4-tert-butylphenol, bisphenol F diglycidyl ether (BFDGE) and bisphenol A diglycidyl ether (BADGE) in mineral water with fluorometric detector is described in this paper. After pretreatment through solid-liquid extraction, the sample was analyzed by HPLC. The operating conditions were Turner C18, 5 microns, column, 150 mm x 4.6 mm i.d., mobile phase with V (ACN): V (water) = 40:60 for 10 min, then linear gradient elution for 25 min up to 80:20 with a flow rate of 1.3 mL/min. Excitation wavelength was set at 275 nm and emmission at 300 nm. The recoveries were 81%-105% and the RSDs were 1.12%-13.21%. Detection limit reached 0.1-0.2 microgram/L. |
