Abstract
The application belongs to the technical field of food safety detection, and specifically discloses a method for detecting BaP in edible oil by using CTAB modified silver nanomaterial based on LLE-SERS, which comprises the following steps: preparing Ag nanoparticle sol, preparing CTAB functionalized Ag nanoparticle sol, SERS detection of BaP standard aqueous solution with different concentrations, fitting a standard curve, extracting BaP and performing SERS detection. The synthetic raw materials of the surface CTAB functionalized Ag nanoparticles used in the application are simple, and the coverage degree of the ligand molecules CTAB on the surface of the Ag nanoparticles can be controlled and adjusted. The CTAB as the surface ligand can directly capture and enrich BaP molecules. The detection method is high in stability, and can effectively avoid the problem that different batches of samples produce different effects in the Raman test.
