Abstract
Magnetic microspheres with chitosan (CTS) and nano-iron (NI) as materials were synthesized by reverse suspension polymerization technology, and then modified with ethylenediamine (EDA). The average amine content of as-prepared magnetic microspheres (CTS-NI-MM-EDA) is 5.22 mmol/g, and the iron content is 23.77%.The adsorption experiments indicated that the adsorption rate of CTS-NI-MM-EDA for methyl orange is in the range of 62%-86% when the concentration of methyl orange is less than 250 mg/L, and the saturated adsorption quantity is 1651mg/g at 25 oC and pH 5.5.
