The peaks at 556, 1144, 1375, and 1506 cm −1 can be assigned to ν(S–S) band, ρ (HCN)+(CH 3 ), δ s (CH 3 ) coupled with ν(C–N) and δ as (CH 3 ) coupled with υ(C–N) of ...
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. WebSep 1, 2024 · As shown in Figure 4f, SERS spectra of thiram clearly demonstrated the shell thickness-dependent sensitivity of SERS detection. As the amounts of HAuCl 4 increased from 200 μL to 800 μL, SERS activity of the obtained core-shell substrates with the decreased thickness shell from 29.41 nm to 5.88 nm was increased to the maximum.
