TY - JOUR TI - Adsorptive Removal of Tartrazine Dye by Poly(N-vinylimidazole-ethylene glycol dimethacrylate) And Poly(2-hydroxyethyl methacrylate-ethylene glycol dimethacrylate) Polymers AB - Poly(N-vinylimidazole-ethylene glycol dimethacrylate (poly(N-VI-EGDMA)) and poly(2-hydroxyethyl methacrylate-ethylene glycol dimethacrylate (poly(HEMA-EGDMA)) were synthesized as adsorbents for adsorptive removal of tartrazine dye from aqueous solutions. To achieve maximum tartrazine adsorption, some parameters were examined and pH was found to be an important factor on adsorption poly(N-VI-EGDMA). As the temperature increased, removal amount of tartrazine was increased. The experimental capacities were found as 265.5 mg/g and 45.15 mg/g for poly(N-VI-EGDMA) and poly(HEMA-EGDMA), respectively. The experimental data well correlated with Freundlich isotherm.The estimated ∆Hº values were found as 12.76 kJ/mol and 10.40 kJ/mol for poly(N-VI-EGDMA) and poly(HEMA-EGDMA), respectively. Adsorption was demonstrated to be endothermic in nature. The characterization of these polymers were done by using FTIR, TGA and SEM analysis.
