摘要
目的建立同时测定水中双酚A、辛基酚、4-壬基酚的高效液相色谱荧光检测法。方法样品经液-液萃取，采用XTerraRP18色谱柱（4．6mm×150mm，5μm），以甲醇-水（体积比为80：20）为流动相，高效液相色谱荧光检测器进行检测。结果双酚A、辛基酚、4-壬基酚的检出限为0．01—0．02μg／L，平均回收率为82．8％～97．8％，相对标准偏差为1．26％-4．14％。结论该方法操作简便，回收率高，重复性好，适用于水中双酚A、辛基酚、4-壬基酚的同时检测。
Objective To develop an efficient method for the analysis of bisphenol A, 4-n-octylphenol and 4-Nonylphenol in the water. Methods With liquid-liquid extraction, the target compounds were separated on an XTerra RP18 column（150 mm4.6 mm, 5 μm） by using water-methanol （20：80, V/V） as the mobile phase, detected with fluorescence, the fluorescence excitation. Results The linear ranges of determination were 0.01-0.02 μg/L, the average recoveries were 82.8%-97.8%, relative standard deviations were 1.26%-4.14%. Conclusion The method is applicable to simultaneous determination of bisphenol A, 4-n-octylphenol and 4-Nonylphenol in water with simplicity and accuracy in a single injection.
