Thiram sers

WebBy measuring the Thiram's characteristic peak intensity at 1371 cm-1, the SERS method could distinguish Thiram from other pesticide residues. A good linear relationship between the peak intensity at 1371 cm-1 and thiram's concentration was established at the range from 0.01 ppm to 100 ppm and the Limit of detection is 0.0048 ppm. WebOct 17, 2024 · The SERS spectra of thiram of different concentrations are shown in Figure 4B. The quantitative analysis showed the increase in spectral intensity with the rise in the concentration of thiram. Notably, the as-prepared [email protected] NRs arrays substrate could detect thiram as low as 10 −9 mol/L, with a LOD of 0.018 mg/L.
