摘要
建立纺织品中偶氮染料的表面增强拉曼光谱快速筛查方法。以24种芳香胺为研究对象,利用表面增强拉曼光谱技术,结合使用金纳米粒子增强剂,对纺织品中的偶氮染料进行检测。通过对样品纳米金溶胶的用量、缓冲溶液种类和pH值的优化,确定了最佳优化条件:纳米金溶胶的用量为50μL,缓冲溶液为柠檬酸溶液,pH值为6.0。同时对24种芳香胺的特征峰进行采集、分析和分类,确定分为以下几类:苯胺类、联苯类、含硝基类、萘类。该方法操作简单,易于掌握,可以快速筛选出纺织品中的偶氮染料。
A rapid method of surface enhanced Raman spectrodcopy was established to screening azo dyes in textiles.24 kinds of aromatic amines were studied.The azo dyes in textiles were probed by surface enhanced Raman spectroscopy employing gold nanoparticles as the enhancer.By optimizing the amount of gold nanoparticles,the type of buffer solution and the pH value,the optimization testing conditions were determined.The dosage of gold-collosol was 50 uL,while the buffer solution was a citric acid buffer solution,and the pH value was 6.Furthermore,the characteristic peaks of banned aromatic amines were collected and analyzed,which were classified into the species of aniline,biphenyl,nitro group and naphthalene.The proposed method is simple and easy to master,which can be used for fast screening of azo dyes in textiles.
