摘 要:采用两步法将皮革中的壬基酚(NP)和壬基酚聚氧乙烯醚(NPnEO)分别萃取出来,然后利用GC-MS对两种物质进行测定。第一步采用正己烷对样品中的NP萃取;第二步采用丙酮对样品中NPnEO萃取。索氏抽提和超声波萃取均可作为壬基酚类物质萃取的方式;索氏抽提因作用缓和、萃取物中杂质较少而更适合。采用优化后的萃取方法对皮革样品中壬基酚类物质进行检测,结果表明皮革样品中无NP,但NPnEO含量显著。The nonylphenols(NP) and ethoxylated nonylphenols(NPnEO) in leather were extracted individually by two steps and their contents were tested by GC-MS.The results presented that hexane was suitable for the extraction of NP and acetone was suitable for the extraction of NPnEO.Both Soxhlet and ultrasonic could be used for the extraction of NP and NPnEO in leather.However,Soxhlet was suitable for the extraction due to its mild action.The contents of NP and NPnEO were tested with the optimized extraction method.T...
