Sorption concentration of copper, lead, and iron on carriers modified by 8-hydroxyquinoline and its derivatives

Sorption of copper, lead, and iron ions on carriers (silochrome S-120, anion exchanger AB-17, enterosgel, polysorb) noncovalently modified by 8-hydroxynoline, 5,7-dibrom-8-hydroxyquinoline, and 8-hydroxynoline-5-sulfo-acid has been studied. Optimal sorption conditions have been found. The determination is not impeded by a 103-fold excess of potassium, natrium, calcium and magnesium. The methods have been tested on water and soil samples from Saransk city. The systematic error of determination was assessed with the use of model solutions in the option introduced/found. The relative standard deviation does not exceed 0.08 (n = 5).
