中文摘要：
以可溶性淀粉为原料，在反相悬浮体系中合成N，NL亚甲基双丙烯酰胺交联淀粉微球（CSM）为载体。研究淀粉微球对Fe^2＋的吸附行为，利用红外（FT-IR）、扫描电镜（SEM）、X射线衍射仪（XRD）对微球及其吸附产物进行表征，研究其吸附机理。结果表明：淀粉微球对Fe^2＋吸附等温线符合Langmuir等温方程，对其吸附等温线进行拟合，相关性较好。在室温条件下，pH值为4．5，对Fe^2＋的吸附时间为60min，最大吸附量为0．866mmol／g，得出吸附速率方程，吸附Fe^2＋后微球结晶度降低。
英文摘要：
The N, N＇ -methylenebisacrylamide cross-linked starch microspheres （CSM） were synthesized from soluble starch in inverse suspension system. Then the starch microspheres and its adsorption behavior to iron （Ⅱ） were characterized using scan electron microscope （SEM）, Fr-IR spectroscopy and X-ray diffractometer, and the mechanism of adsorption was also discussed in the present study. The results showed that the adsorption behavior of the starch microspheres to iron （Ⅱ） ions was adapted to Langmiur adsorption isotherm equation with nice correlations. At room temperature and pH 4.5, the maximum absorption amount of starch microspheres to iron （Ⅱ） ions was 0.866 mmol/g within 60 rain. Meanwhile, the adsorption rate equation was deduced. The crystaUinity of microspheres decreased after the absorption to iron （Ⅱ） ions.
