Crosslinked starch microspheres ( CSM) were prepared in a microwave-assisted inversed emulsion system, using methyl violet ( MV) as a targed compound, the influence of the CSM conditions of preparation, such as starch, cross-linking agent, initiator, polymerization temperature and polymerization time on MV removal efficiency was evaluated. The structure and morphology of starch microspheres were characterized by scanning electron microscope ( SEM ) , FT-IR spectroscopy and BET surface area measurement. In addition, the adsorption efficiency of ...
