The dynamics of seasonal and annual changes in the concentration of iron (III) ions in the waters of the Kungirot district of the Republic of Karakalpakstan were analyzed. A method for determining iron (III) ions using immobilized organic reagents containing nitrogen and oxygen was proposed. The sorption-spectrophotometric method was compared with other methods, and the t and F criteria were determined. Favorable conditions for the immobilization of organic reagents were identified. Scanning electron microscope images of the immobilized organic reagent, sorbent, and the formed iron (III) ion complex were captured.
