Research into the sorption of perrhenate ions by aminoquinoid redox-polymers

The synthesis features and the properties of an aminoquinoid redox-polymer based on Polyethyleneimine and Chloranil have been studied. The structure of a redox-polymer so obtained has been corroborated by elemental analysis and IR-spectroscopy data. The sorption capacity of samples with respect to perrhenate ions has been studied through polarography. Sorption has been observed on the basis of model solutions NH₄ReO₄, at different pH, various concentrations of primary solutions and different duration of exposure. Comparative data in respect of the sorption of perrhenate ions by industrial designs are set forth herein.
