Abstract

Superparamagnetic microspheres of poly(glycidyl methacrylate-co-divinylbenzene) were produced via suspension polymerization and were functionalized with ethylenediamine, diethylenetriamine and triethylenetetramine. The results of Cr(VI) adsorption showed better removal at pH 2. The adsorptive process was best described by the pseudo-second order model, and an equilibrium isotherm study indicated the best suitability of the Langmuir model. The microspheres modified with ethylenediamine had greater adsorption capacity and the highest ΔH value at pH=2 and 318 K. The choice among EDA, DETA, and TETA as substituent groups depends on balancing adsorption efficiency, selectivity and process kinetics. In these studies, R14-DETA showed better performance than the others. The adsorbents had ΔH around 40-45 kJ/mol and ΔS between 148-159 J/mol.K. The results indicated an endothermic process, of chemical nature, with negative ΔG values. This study indicates the potential for applications in Cr(VI) removal.
