Poster summary

At present, the interest of analytical chemists in metal-containing nanocomposites has increased significantly. This is primarily due to the possibility of their application as optical sensors. The operation of such sensors is based on the phenomenon of surface plasmon resonance (SPR). The result of this study is the development of a new sensitive method for the determination of iodide ions based on the use of paper modified with silver nanoparticles (NPs). Iodides, oxidized under the action of special reagents, form molecular iodine, which is extracted by an air flow and transferred to a sensitive paper layer containing NPs. The interaction of NPs with iodine leads to traceable optical changes. The limit of detection (0.01 mg/L) and the range of determined concentrations (0.03–1.6 mg/L) of iodide ions were determined.
