| 摘 要： | 建立了一种柱前衍生／超高效液相色谱分析方法，对一次性纸杯浸泡液中痕量甲醛进行了测定，并对衍生化条件、衍生化产物的提取条件和色谱分离条件进行了优化。该方法在O．052~2．080mg／L范围内具有良好的线性关系，线性方程为A=37369c＋267．5，线性相关系数为0．9999，检出限为O．010mg／L（S／N-3）。采用该方法对市售的一次性纸杯浸泡液中甲醛含量进行检测，发现一次性纸杯浸泡液中甲醛含量均很低，可以安全使用。

| Abstract: | A HPLC method was established to determine the leached trace formaldehyde in disposable paper cups using ultra performance liquid chromatography （UPLC） coupled with pre-column derivation technique. The derivation conditions, the extraction conditions of the derivative products and the chromatography conditions were optimized. The method had a good linear relationship between the range of 0.052 to 2.080 mg/L. The linear equation was A=37369c＋267.5 with a linear correlation coefficient of 0,9999. The detection limit was 0.010 mg/L at the condition of S/N （signal/noise=3）. Some commercially available disposable paper cups were analyzed using the method. The results showed that the disposable paper cups could be used safely, only with quite little formaldehyde leached. |
