This article proposes a simple and rapid method for the spectrophotometric determination of iron (III) using a physiologically active compound - the mono ammonium salt of glycyrrhizic acid (MASGA). The spectral characteristics of the MASGK-Fe (III) complex - absorption maxima (λmax = 440nm) and the actual molar extinction coefficient (ε = 3,425 × 102) were determined. The experimental results showed that when using a universal buffer solution, the complex compound had the maximum optical density. Therefore, in subsequent studies, a universal buffer solution with pH = 5 was used. The experimental results showed that the optical density of the complex …
