| 中文摘要: |
| 建立了一种高效液相色谱-荧光检测法测定金属食品罐用涂料中双酚 A 的定量分析方法。 样品用甲醇超声提取,双酚 A 在质量浓度为 0. 1 ~20. 0 μg/ mL 范围内,峰面积与质量浓度具有良好的线性关系,线性方程为 y=19. 241x+2. 7916,相关系数为 0. 9985,检测限为 0. 05 μg/ mL,回收率为 95. 0% ~100. 9% 。 分析比较了不同厂家和不同批号涂料中双酚 A 的含量。 研究表明,该方法灵敏可靠,准确度高,适用于定量检测金属食品罐用涂料中的双酚 A。 |
| 英文摘要: |
| A method was established for determining bisphenol A (BPA) in coatings of metal food cans by high performance liquid chromatography with fluorescence detection. Samples were ultrasonic extracted with methanol. The peak area and concentration of BPA has a better linear relationship in the range of 0. 1 μg/ mL to 20. 0 μg/ mL ( r = 0. 9985). The linear equation is y=19. 241x+2. 7916. The limit of detection is 0. 05 μg/ mL. Recovery of the method is 95. 0% ~100. 9% . The BPA contents of several batches coating from different suppliers were compared. It was concluded that the method is sensitive, reliable, accurate and fit for BPA quantitative determination in metal food cans. |
