| 目的 研究重复使用条件下聚碳酸酯（PC）饮水桶中双酚A（BPA）的迁移规律及主要影响因素，为日常生活中PC饮水桶的正确使用提供参考。方法 采用高效液相色谱方法， 研究了重复使用时间、温度和换水间隔对收集的5只饮水桶中BPA迁移行为的影响， 同时分析新桶与使用1年的旧桶的区别。结果 PC饮水桶中BPA的迁移主要受重复使用时间和温度的影响， 并且随使用时间的延长和温度的升高而增加； 间隔换水时间对BPA迁移影响较小； 已使用过的PC旧桶中BPA迁移量显著高于新桶。结论 在PC桶的日常使用中， 应注意在常温下短期使用， 避免高温长期使用， 使用一段时间的PC桶应注意废弃回收。 |
| 英文摘要: |
| The aim of this study was to investigate the main influencing factors and behaviors of Bisphenol A (BPA) migration from Polycarbonate (PC) drinking bucket under the repeated use condition, thus to provide reference for correct use of PC drinking bucket in the daily life. Using high performance liquid chromatography (HPLC), the influence of reused terms, temperature and interval time of changing water on BPA migration from the five collected drinking buckets was studied. In the meantime, the difference between the new PC bucket and old PC bucket used for one year was analyzed. The migration of BPA from PC buckets was mainly affected by the use terms and temperature. The migration amount increased with the reused terms and temperature. The interval time of changing water had little influence on the BPA migration. Also, the amount of BPA migration from the reused old PC bucket was apparently higher than that from the new PC bucket. During the daily use of PC buckets, they should be used at normal temperature for short terms, in avoid of high temperature and long terms. After being used for some terms, PC buckets should be discarded and recycled. |
