DETERMINATION OF LEAD IONS USING AZO DERIVATIVES OF GOSSYPOL
The article reveals the advantages of using gossypol and its azo derivatives as a lead ion agent. A simple and express method for
the spectrophotometric determination of lead ions using azo derivatives of gossypol is presented. The optimal conditions for
spectrophotometric determination were determined, a graduated graph with a linear relationship between the optical density and
lead concentration (2.0–50.0 μg/25 ml) was constructed under the established optimal conditions, the composition and stability
constant of the complex of the metal ion with the gossypolase derivative were determined.
