摘　　要：利用一种新型平行真空浓缩仪代替纺织品禁用偶氮染料检测前处理过程中的旋转蒸发仪,可实现浓缩的批量化处理,提高检测效率。在规定条件下,平行真空浓缩仪对标准规定的24种芳香胺的回收率在64.5%~94.0%之间,满足测试要求;一次性浓缩6个样品的时间为7.5 min,平均一个样品的浓缩时间约为1.3 min,是传统旋转蒸发仪耗时的1/6;乙醚的回收率高达75%以上,避免了乙醚过量挥发在实验环境中。在模拟样品测试中,典型胺类物质的回收率明显优于标准规定。A new parallel vacuum concentrator was used to replace the rotary evaporator in the pretreatment process of detecting banned azo dyes in textiles,which could realize the batch treatment of concentration and improve the detection efficiency.Under the specified conditions,the recovery of 24 aromatic amines specified in the standard by the parallel vacuum concentrator was 64.5%~94.0%,which met the test requirements.The concentration time of six samples was 7.5 min,and the average concentration time of one sample was about 1.3 min,which was 1/6 of the traditional rotary evaporation time.At the same time,the recovery of ether was more than 75%,avoiding excessive evaporation of ether in the experimental environment.In the simulated sample test,the recovery of typical amines was obviously better than the standard.
