中文摘要：
在反相悬浮体系中以K_2S_2O_8-NaHSO_3引发N,N'-亚甲基双丙烯酰胺与淀粉的接枝共聚,制备淀粉接枝共聚物微球,研究微球对Cd~(2+)的吸附行为,利用红外、SEM、X射线衍射仪和综合热分析仪对微球及其吸附产物进行表征,研究吸附机理。结果表明:微球对Cd~(2+)吸附行为符合Langmiur方程和Freundlich方程;吸附Cd~(2+)使微球的结晶结构被进一步破坏,结晶度下降,同时促进了微球中主链断裂。
英文摘要：
Starch graft copolymer microspheres were synthesized by inverse suspension polymerization with N,N - methylenebisacrylamide and soluble starch,using K_2S_2O_8-NaHSO_3 as initiator.The adsorption behavior of starch graft copolymer microspheres to Cd~(2+) was investigated.The starch graft copolymer microspheres and their adsorption products were characterized with scan electron microscope (SEM),FT-IR spectroscopy,X-ray diffraction (XRD),and thermogravimetric analysis (TGA). The results showed that the adsorpt...
