摘要
用带荧光检测器的高效液相色谱法同时测定了矿泉水中的苯酚、甲酚、双酚Ａ、双酚Ｆ、４－叔丁酚、双酚Ａ二环氧甘油醚和双酚Ｆ二环氧甘油醚等，水样经液－固萃取浓缩后再进行分析，检测限可达０．１～０．２μｇ／Ｌ。重复测定的标准偏差为１．１２％～１３．２１％，水样测定的回收率为８１％～１０５％。
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 C 18 , 5 μm, column, 150 mm×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 RSD s were 1 12% 13 21%. Detection 1imit reached 0 1 0 2 μg/L.
