In this paper, gemini polymeric nanoarchitecture (GPN) as a novel adsorbent was synthesized, and its dye removal ability from single and multicomponent (ternary) systems was investigated. The physical characteristics of GPN were studied using Fourier transform infrared (FTIR). Acid Blue 92 (AB92), Direct Green 6 (DG6), and Direct Red 31 (DR31) were used as model compounds. The isotherm and kinetic of dye adsorption from single and multicomponent (ternary) systems were studied. The effect of operational parameter such as adsorbent dosage, dye concentration, and salt on dye removal was evaluated. The maximum dye adsorption capacity (Q(o)) of GPN was 1000 mg/g, 1428 mg/g, and 1250 mg/g for AB92, DG6, and DR31, respectively. It was found that adsorption of AB92, DG6, and DR31 onto GPN followed with Langmuir, Freundlich, and Langmuir isotherms, respectively. Adsorption kinetic of dyes followed pseudo-second order kinetics. The results showed that the GPN as an insoluble polymeric adsorbent with high dye adsorption capacity might be a suitable alternative to remove dyes from colored wastewater. (C) 2013 Elsevier Inc.
