摘　　要：将固相萃取技术应用于禁用偶氮染料中代谢物苯胺类物质的检测。采用自制的大孔吸附树脂固相萃取小柱可以同时吸附水体中的苯胺类物质和其他常用染料。HPD系列大孔吸附树脂对苯胺类物质的吸附量大于对染料的吸附量,解脱性良好,适宜于做本方法的固定相。利用丙酮和乙醇2种溶剂的不同极性,将染料与苯胺类物质进行洗脱分离,解脱率较高,适宜做本方法的洗脱剂。通过紫外吸收光谱法和高效液相色谱法进行定性、定量检测,初步建立起一套快速、简单、实用的分离检测方法。Solid phase extraction method was applied for separation and analysis of banned azo dyestuffs and its reduction product-anilines.The results show that anilines and dyestuffs can be absorbed by the suitable stationary phase macroporous absorption resin in aqueous solution at the same time.Meanwhile,two parts can be easily separated basing on the different polarity between acetone and ethanol.Then it can get their properties and amounts measurement by ultraviolet absorption spectrometry and high performance l...
