SPECTROPHOTOMETRIC DETERMINATION OF TRACE AMOUNTS OF SILVER(I) IONS USING H-RESORCINOL

Аннотация

A new organic reagent, H-resorcinol, was employed as a highly sensitive, selective, and rapid-acting reagent for the determination of silver (I) ions. The interaction of silver (I) with H resorcinol occurs through the formation of a stable coordination bond. At pH = 10, an ammonia buffer solution was used as a background electrolyte, resulting in the formation of a 1:1 (silver:H-resorcinol) molar ratio complex. This approach is of particular importance, as the reliable and selective determination of trace silver ions holds significant analytical value in environmental monitoring, pharmaceutical analysis, and industrial quality control, where the accurate detection of even very low concentrations of silver is essential.
