摘　　要：胂烷、膦烷是造成聚合级烯烃在聚合过程中催化剂失效的重要原因之一,目前,大多采用氧化铝基球形吸附剂吸附烯烃中胂烷、膦烷以及硫化物等,以防止催化剂中毒。目前常用的方法有吸收富集分光光度法、吸收富集电感耦合原子发射光谱仪(ICP-AES)、原子荧光法测定,现对最新测定技术气相色谱-电感等离子体-质谱仪(GC-ICP-MS)、气相色谱原子发射光谱联用仪(GC-AED)、氦离子化气相色谱仪(GC-DID)、气相色谱质谱联用仪(GC-MS)进行介绍。Arsine,phosphine is one of the important causes of failure of the olefin polymerization stage during polymerization catalyst.At present,most of the alumina-based adsorbent spherical olefins alkyl arsine,phosphine and alkyl sulfides,etc.,in order to prevent catalyst poisoning.The most commonly used method of enrichment absorption spectrophotometry,absorption and accumulation in ICP-AES,atomic fluorescence spectrometry.Now introduced the latest measurement techniques GC-ICP-MS、GC-AED、GC-DID、GC-MS.
