| 摘要: |
| 介绍了一种可以快速鉴定食品金属包装用涂料中双酚 A 的方法。 通过分析样品的红外吸收光谱图,比对双酚 A 结构中特有的 5 种官能团的特征峰,即可判断出该涂料是否以双酚 A 为原材料进行加工。 该方法快速、简便、准确,符合包装涂料使用者对原材料的定性鉴定要求。 |

| Abstract: |
| A quick analysis method of bisphenol A (BPA) in the coating of food metal packaging was established. It can judged whether the coating was produced with BPA as raw material by analyzing the infrared absorption spectrum of the samples and comparing the five characteristic peaks of peculiar functional groups in the BPA's structure. The method is very quick, simple, and accurate, meeting coating users' requirements of qualitative appraisal of raw materials. |
| Key words: bisphenol A coating infrared spectrum qualitative inspection |
