Construction of AuNRs/MoS_(2)/Silica gel thin-layer chromatographic plates combined with SERS technology for point-array detection of benzo(a)pyrene in complex aqueous bodies

苯并芘(Bap)是环境中典型的有机污染物,通过生物循环途径在人体内富集,会对机体造成慢性损伤。为了快速痕量分析复杂环境中的苯并芘,本工作将薄层色谱板(TLC)与表面增强拉曼散射(SERS)技术相结合,构建了一种新型AuNRs/MoS_(2)/Silica gel薄层色谱板,并将其应用于Bap的痕量检测。该方法具有灵敏度高、操作简便等优点,可以完成对毒物的现场快速分析检测,有效克服了目前苯并芘检测方法中检出限高、仪器设备昂贵等问题,具有一定的实际意义。

Benzo(a)pyrene(Bap)is a typical organic pollutant in the environment,which is enriched in the human body through continuous biological cycles and can cause chronic damage to the organism.In order to rapidly detect benzopyrene and complete trace analysis,a new disposable sensor for the separation and detection of poisons was constructed by combining thin layer chromatography plates(TLC)with surface-enhanced Raman scattering(SERS)to detect benzopyrene.This method has high sensitivity,easy operation and other advantages.It can complete the on-site rapid analysis and detection of poisons,and effectively overcome the problems of difficult operation and high technical requirements of the current detection method for benzopyrene,which has certain practical significance.
