摘要 | A green, simple and sensitive method was developed for the analysis of volatile carboxylic acids (VFAs) and perfluorocarboxylic acids (PFCAs) in food packaging materials. The acidic compounds in food packaging materials were first extracted by gas purge microsyringe extraction (GP-MSE) with 1.0 mL 0.1 mol center dot L-1 NaOH solution, then the analytes were dispersive liquid-liquid microextracted (DLLME) by 50 mu L chloroform as extraction solvent and 200 mu L acetonitrile as dispersive solvent. The 2-(5-Benzoacridine) ethyl-p-toluenesulfonate (BAETS) with excellent fluorescence property was applied to enhance the high performance liquid chromatography (HPLC) sensitivity. The obtained recoveries for the VFAs ranged from 92.0 to 101 %. The method LODs calculated at a signal-to-noise ratio (S/N) of 3 were in the range of 0.80-3.40 mu g center dot kg(-1), while the LOQs calculated at S/N of 10 were in the range of 2.5-10.2 mu g center dot kg(-1). All compounds were in good linearity with concentration coefficients of higher than 0.997. Perfluorooctanoic acid (PFOA) was found in all of the 15 kinds of samples analyzed with concentrations ranging from 4.86-7.56 mu g center dot kg(-1). Acetic acid, butyric acid, and caprylic acid were found in half of the samples analyzed. The other analytes were also found in more than 30 % samples with concentrations varied between 3.96 and 293 mu g center dot kg(-1). |
