The proposed work describes the nanodrop spectrophotometric determination of cationic surfactants using citrate-modified silver nanoparticles based on the aggregation of silver nanoparticles induced by cationic surfactants due to the hydrophobic effect. The visible color change in the solution of silver nanoparticle includes a red shift with the quenching of the absorption spectra. The maximum absorbance was measured at wavelength, λ max 400 nm. The concentrations of cationic surfactants were determined using a nanodrop spectrophotometer with limits of detection of 15.0, 8.0, 6.0, 5.8, and 13.0 µM for dodecyl trimethyl ammonium bromide, myristil trimethyl ammonium bromide, cetrimonium trimethyl ammonium bromide, cetyl pyridinium chloride and benzalkonium chloride, respectively. The proposed method was successfully applied for the determination of cetyl pyridinium chloride in commercial mouthwasher, gum astringent and nasal spray pharmaceuticals and environmental samples.

Determination of very low amounts of free copper and nickel ions in beverages and water samples using cloud point extraction assisted by silver nanoparticles

2015

Silver nanoparticles (AgNPs), functionalized with the sodium salt of 2-mercaptoethanesulfonic acid (MESNA), can be used in a cloud point extraction process with Triton X-114 to transfer low amounts of copper and nickel ions to the surfactantrich phase. Both metals are then measured in the coacervate by electrothermal atomic absorption spectrometry. For a 20 mL aqueous phase containing a low concentration (100 μg L -1 ) of the functionalized AgNPs and 0.15% Triton X-114, an enrichment factor of 510 is achieved. The detection limits are 2.4 and 2.1 ng L -1 for copper and nickel, respectively. The reliability of the procedure is verified by analyzing three water samples with certified copper and nickel contents. The procedure is also applied to the determination of these analytes in wine and beer samples. The results indicate that only free or labile ionic copper and nickel species are transferred to the coacervate, thus providing a way for the rapid fractionation of these compounds without the need for a previous solid phase extraction stage.

“…25 Currently, silver nanoparticles (AgNPs) provide a simple and low-cost solution for the rapid detection of heavy ions. [26][27][28][29][30] However, in most cases, only one kind of heavy metal ion is detected using the above strategy. Moreover, a series of other reagents is also necessary for the selective detection of heavy metal ions.…”

Perylene dye-functionalized silver nanoparticles serving as pH-dependent metal sensor systems

et al. 2017

Lysine-functionalized perylene was used to modify nanoparticles. Due to the benefits from a synergetic effect that originated between the perylene and silver nanoparticles, color-based metal sensor systems were established. At pH ¼ 12.6, Cr 6+ with a concentration of 100 nM could be detected by a color change from deep yellow to orange; after decreasing the pH to 12.0, the detection limit decreased to 2 mM. Interestingly, after further decreasing the pH to 11.0, another kind of metal ion (Cd 2+ ) could be recognized with a detection concentration of 10 mM. At pH ¼ 10.0, Pb 2+ with a concentration of 2 mM could be detected.
