摘　　要：纺织品禁用偶氮快速检测前处理相比于传统的固相萃取与氮吹结合的处理方法有着很大的变革,操作上摒弃了提取柱吸附与氮吹处理带来的技术难度,降低人为误差;物料损耗方面,技术步骤的简略带来了经济效益的提高,减少了大量试剂对样品目标化合物的洗脱与浓缩,包括其他试验耗材的使用等,有效节约成本与保护环境。此外,由于减少部分操作带来的目标化合物损失,在测试中禁用偶氮的测试回收率有所增加,痕量检出率也有所提升;通过一系列试验数据、对比试验周期与损耗对比进行分析,供大家参考。The pretreatment process for rapid detection of azo dyes prohibited in textiles has undergone significant changes compared to the traditional method combining solid-phase extraction with nitrogen blowing.It discards the technical difficulties brought by extraction column adsorption and nitrogen blowing,thus reducing human errors.In terms of material loss,the simplified technical steps have brought about economic benefits,reduced the elution and concentration of target compounds in samples by a large number of reagents,including the use of other experimental consumables,effectively saving costs and protecting the environment.In addition,due to the reduction of target compound loss caused by some operations,the recovery rate of prohibited azo dyes in the test has increased,and the trace detection rate has also improved.A series of experimental data,comparison of experimental cycles,and loss comparison are analyzed for your reference.
