摘要
利用色质联用技术对尼龙6在超临界水中的降解产物进行了定性分析,对己内酰胺进行了定量分析。结果表明,液相降解产物主要是己内酰胺,此外还有少量其他小分子物质。定量检测方法前期处理简单快捷,易于操作。方法重现性良好,保留时间的RSD仅为0.64%,峰面积的RSD为3.58%。
Degradated products of nylon 6 in supercritical water were analyzed by GC-MS. The composition of degradated products was identified and ε-caprolactam was determined quantitatively. The test results showed that the main product of degradated nylon 6 was ε-caprolactam and other products were some low molecular weight substances. The sample preparation is simple, rapid and easy to operate. The reproducibility of the method is good, the RSD of retention time is 0.64% and the RSD of peak area is 3.58%.
