  • 摘要: 以甲基紫吸附去除效率作为考核指标,研究了淀粉(ST)、交联剂N,N'-亚甲基双丙烯酰胺(MBAA)、引发剂 (K2S2O8/NaHSO3)用量、聚合温度以及聚合反应时间等因素对微波辅助反相乳液法制备交联淀粉微球(CSM)的影响,利用傅里叶红外光谱仪(FT-IR)、电镜扫描仪(SEM)、比表面积分析仪等对CSM进行了表征,对比了优化条件下水浴和微波两种不同加热方式合成CSM的吸附效率.结果表明,MBAA成功与淀粉交联成类球状聚合物,聚合微球平均粒径约为9.253 μm,聚合微球明显增加了微孔面积,微波加热合成的CSM对甲基紫的吸附率高于水浴加热合成的CSM.
    Abstract: Crosslinked starch microspheres (CSM) were prepared in a microwave-assisted inversed emulsion system, using methyl violet (MV) as a targed compound, the influence of the CSM conditions of preparation, such as starch, cross-linking agent,initiator,polymerization temperature and polymerization time on MV removal efficiency was evaluated. The structure and morphology of starch microspheres were characterized by scanning electron microscope (SEM),FT-IR spectroscopy and BET surface area measurement. In addition, the adsorption efficiency of starch microspheres prepared by microwave heating and water bath heating were compared. The results indicated that the starch was successfully cross-linked in near-spherical polymer with MBAA,and the average particle diameter was 9.2 μm. Compared with native starch, the polymer dramatically increased micro hole area.The adsorption efficiency of the polymer prepared by microwave heating for methyl violet was higher than that prepared by bath water heating.
