THE SORPTION-SPECTROSCOPIC METHOD FOR DETERMINING CHROMIUM(III) IONS USING AN ORGANIC REAGENT
Keywords:
sorption-spectroscopy, immobilization, nitrozo-R-salt, chromium, organic reagents, PPA fiber.Abstract
A sorption-spectroscopic method for determining chromium (III) ions in industrial wastewater was developed. The immobilization methodology was presented, and a suitable carrier for immobilization was selected. The dependence of the complex formation of chromium (III) ions with an organic reagent on the pH environment was studied. The structure of the complex formed with the immobilized nitrozo-R-salt reagent and the immobilization mechanism of the reagent onto the fiber were confirmed using X-ray fluorescence analysis.
