摘要
采用固相微萃取(SPME)高效液相色谱法(HPLC)同时测定了水中苯酚、4-硝基酚、3-甲基酚、2,4-二氯酚、2,4,6-三氯酚、五氯酚等六种酚类化合物的含量。采用ZORBOXSB—C18柱,以甲醇-1%乙酸水溶液为流动相进行梯度洗脱,流速为1.0mL/min。紫外检测波长为254、280nm。六种酚类化合物的检出限为0.31~1.90μg/L,加标回收率为88%~103%。该方法操作简单.能快竦、缝确她枪测水巾的酚娄化合物.
A solid phase microextraction with high performance liquid chromatography (SPME - HPLC) method was used for the simultaneous determination of six phenols in water, including phenol, 4- nitrophenol, 3-methylphenol, 2,4-dichlorophenol, 2,4,6-trichlorophenol and pentachlorophenol. The chromatographic analysis was carried out using a ZORBOX SB-C18 column. Gradient elution was adopted with the mobile phase consisting of methanol and 1% acetic acid solution. The flow rate is 1.0 mL/min and the wavelengths of UV detector are 254 nm and 280 nm. The detection limits of the six phenols are 0.31 - 1.90 μg/L. The recoveries of the standard addition tests for the six phenols are 88% - 103%. The method is simple in operation and can detect the phenols in water rapidly and accurately.
