摘要: A method for fast extracting an organic pollutant in a complex system is disclosed, which includes following steps. A surface-enhanced Raman scattering (SERS) spectrum of an organic pollutant is divided to obtain P wavelength sub-intervals with overlapping regions. The P wavelength sub-intervals are screened to obtain ω wavelength sub-intervals. The ω wavelength sub-intervals are screened to obtain a required wavelength sub-interval. The required wavelength sub-interval is screened to obtain a required wavelength subset. A method and a system for fast detecting an organic pollutant in a complex system are also disclosed.

摘要: 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.
