Abstract

This article provides a comprehensive review of the relationship between azo reagents and silver nanoparticles (AgNP), highlighting significant advances in analytical chemistry and materials science. The integration of silver nanoparticles with azo compounds has shown remarkable improvements in sensitivity, selectivity, and catalytic activity, leading to new applications in various fields. The article highlights the principles of ultraviolet spectroscopy (UV), discusses experimental methodologies, and elucidates the insights gained into the nature of the complexes formed between silver nanoparticles and azo compounds. Today, the synthesis of silver nanoparticles is widespread due to their many applications in various fields. In the presented article, silver nanoparticles were obtained by the green synthesis method. At the same time, the bisacetylacetonethylenediimine (R) reagent was synthesized and new complexes of nanoparticles were synthesized based on the cetylacetonethylenediimine (CTAB) reagent and acetyl trimethylammonium bromide. The complexes were investigated by UV spectroscopy and the optimal formation conditions were determined. It was determined that the optimal formation of the complex is observed at concentrations of 0.01 M of silver nanoparticles, 10-³ M of the reactant, and 0.5% of the surfactant. UV analysis of the synthesized complexes was conducted, and it was determined that the R reagent gives a maximum peak at the wavelength of 223 nm, 270 nm, 299 nm. During the UV study of the synthesized complexes, it was determined that the binary complex is 227 nm, 272 nm, 308 nm, and the maximum wavelength of the peaks of the ternary complex formed by adding CTAB as a stabilizer is 214 nm, 243 nm, 285 nm.
