Abstract

Poly(acrylo-amidino diethylenediamine) (PADD), fibrous form of anion exchangers, was synthesized to remove Cr(VI). The experimental results were described well by the Langmuir isotherm model (Q_max = 4.67 mmol/g) and pseudo second-order model. The Cr(VI) adsorption capacities were increased by decreasing pH because the –NH₂ in PADD become more positively charged. During five regeneration cycles, Cr(VI) adsorption capacity retained over 95.96% of the initial capacity. Color of the PADD (yellow) changed to green owing to Cr(VI) reduction to Cr(III) and amine transformed into a oxidized form (imine). The PADD was successfully treated Cr(VI) in two different concentrations of industrial wastewater.
