  • Publication number: 20240167959
    Abstract: A method and a system for detecting pesticide residues in tea based on a surface-enhanced Raman scattering (SERS) sensor are provided. An octahedral gold-silver hollow cage-based sensor is prepared, mixed with a pesticide standard solution and analyzed to obtain SERS spectral data. The SERS spectral data is processed, and a quantitative model is established based on the processed SERS spectral data. Based on the quantitative model, the detection of thiram and pymetrozine in tea samples can be completed. By means of an octahedral cuprous oxide template, gold-silver octahedral hollow cage (Au—AgOHCs) nanomaterials are prepared by reduction of gold and silver ions and removal of the template by acid dissolution, so as to prepare the SERS sensor, which can be applied to the rapid and quantitative detection of thiram and pymetrozine in tea samples.
