Synthesis of polymeric beads with tunable size and porosity and their application in removal of Cr(VI)

In the present study we demonstrate a procedure, so-called polymerization in packed bed, for the production of polymeric beads with tunable size and porosity as well as their application in removal of hexavalent chromium. The adsorption was performed in batch mode and the adsorbent capacity was found to be about 120 mg Cr/g dry polymer. The experimental data from the batch binding assay could be described by Langmuir isotherm model. Moreover, scanning electron microscopy (SEM) was performed to examine the particles morphology
