Abstract

Micron-sized monodisperse superparamagnetic polyglycidyl methacrylate (PGMA) particles with functional amino groups were prepared and characterized by SEM, FT-IR and XRD, respectively. The effect of pH value on the adsorption was studied. Their adsorption properties and mechanism for Cr(VI) from wastewater were investigated. In a model system, the adsorption process followed the Langmuir adsorption isotherm, and the maximum sorption capacity of was calculated to be 263.16 mg/g at 308 K and pH 4.5. The adsorption of Cr(VI) capacity reached equilibrium within 15 min and followed pseudo second order kinetics. The adsorption was a spontaneous and endothermic process with ΔH⁰=9.63 kJ/mol.
