Use of silver triangular nanoparticles for the colorimetric determination of ammonium persulfate concentration in water-borne adhesives for cigarettes

Abstract

In this work, a simple method for detecting ammonium persulfate using silver triangular nanoparticles (silver TNPs) was developed. Specifically, silver TNPs exhibited strong/appreciable surface plasmon resonance (SPR) signals at 670 nm, and low concentrations of ammonium persulfate could induce a decrease in the SPR of the silver TNPs and a change in their appearance from blue to colorless. Furthermore, it was also found that the SPR intensity was inversely proportional to the concentration of ammonium persulfate over the range of 0.10–0.70 mmol L−1, with a correlation coefficient of −0.9994. Recoveries for ammonium persulfate in spiked samples were in the range of 94.4–105.8%, and the relative standard deviations (RSDs) were in the range of 3.3–5.6%. Finally, a method for detecting ammonium persulfate using UV-Vis spectrophotometry was established and successfully applied to determining the concentration of ammonium persulfate in water-borne adhesives used in cigarettes.
