摘要
采用气相色谱-电子捕获检测器(GC-ECD) 对皮革中的短链氯化石蜡( SCCPs) 进行测定。结果表明: SCCPs的 GC - ECD 共流出色谱峰保留时间跨度大,仪器响应值表现出对氯含量的依赖; 中链氯化石蜡( MCCPs) 的存在对 SCCPs的分析过程干扰严重; 实际皮革基质非常复杂,导致样品中 SCCPs 的定性困难。
Analysis of short - chain chlorinated paraffins （SCCPs） in leather was studied using gas chromatography combined electron capture detector （GC -ECD）. The results show the wide co -eluting chromatogram of SCCPs, and the response factors are dependent on the degree of chlorination. Significant interference problems from medium - chain chlorinated paraffins （ MC- CPs） are expected due to the difficult chromatographic separation. GC - ECD could not provide satisfactory results for scanning SCCPs in leather because of the low selectivity and the complex matrix influences.
