Application of Immobilized Arsenazo III for Sorption-Spectroscopic Determination of Mercury

The article discusses the credibility of using Arsenazo III immobilized on polyacrylonitrile fiber modified with polyethylene polyamine (PPA) as a reagent for the detection of mercury ions. The optimal conditions for immobilization and complexation have been found. This is due to its high prevalence and stability in the environment, the ability to migrate and bioconcentrate, the high toxicity of most of its compounds.
