The Study of Absorption Behavior on Methyl Orange by Aminated Magnetic Chitosan Microspheres

With chitosan as the raw material,a novel aminated magnetic chitosan microspheres were prepared from chitosan flake through inverse suspension cross-linking in the presence of magnetic particles,then hydroxylpropyl chloridization and amination.The adsorption to methyl orange was analyzed by spectrophotography and adsorption mechanism was briefly discussed.The result indicated that factors of initial concentration of methyl orange、pH value and temperature played an important role in adsorption.It was observe...
