We show the effect of the addition of different salts on the response and enhancement of the Raman signal of triazines. To do this, we have used different monocharged anions (F-, Cl-, Br-, I-) and cations of the alkali metal family (Li+, Na+, K+); as supports, we have used four colloids of silver nanoparticles that were photoreduced with white, purple, blue, and green light filters, and as test analytes, we have used two different triazines (cyanuric acid and sodium trithiocyanurate). The highest Raman enhancement signals were produced by the combination of the smallest nanoparticles obtained (photo-irradiated with blue light) together with the halide anion (I-) and the alkali metal cation (K+). Regarding the analyte, sodium trithiocyanurate registered greater surface-enhanced raman scattering (SERS) improvements than cyanuric acid under these same conditions. Our research highlights the activating role of SERS played by highly polarizable monocharged ions (I- and K+), which facilitate the electronic transfer of metal to the analyte, improving the Raman signal markedly.
