| 摘 要： | 以可溶性淀粉为原料,N,N’-亚甲基双丙烯酰胺为预交联剂,环氧氯丙烷为交联剂,采用反相悬浮聚合得到了一种新型淀粉基吸附材料-淀粉微球,研究了微球对Cr3+的吸附行为。结果表明,微球对Cr3+吸附行为符合Langmiur方程和Freundlich方程;吸附Cr3+使微球的结晶结构被进一步破坏,结晶度下降。

Study on adsorption behavior of novel starch-based adsorption material for chromium ions |

| Abstract: | The starch microspheres were synthesized from soluble starch as raw material through inverse-suspension polymerization,using N,N'-methylenebisacrylamide as precrosslinking agent,epichlorohydrin as the crosslinking agent.Adsorption behavior of starch graft copolymer microspheres for Cr3+ was investigated.The result shows that the adsorption behavior of the copolymer microspheres for Cr3+ is adapted to Langmiur and Freundlich adsorption isotherm equation.After Cr3+ was adsorbed in microspheres,the crystallinity of graft copolymer microspheres decreased. |
