The article describes the features of the reaction of “nitron” with hydroxylamine, hydrazine, hexamethylenediamine and ethylene diamine. The obtained anion-exchange materials and polycomplexones are recommended for the extraction of chromium (VI) and copper (II) ions from wastewater. A polymer reagent containing arsenazo-III is recommended for analysis of heavy-metal ions, iodine-containing anion exchangers were recommended for the treatment of purulent-necrotic diseases of soft tissues complicated by diabetes.
