文档介绍：环氧树脂整体柱的制备和应用
【摘要】:本研究采用环氧树脂作为单体,二乙烯三胺作为环氧树脂的固化剂,聚乙二醇为致孔剂,在内径为1cm,长为10cm的玻璃柱中制备环氧树脂-二乙烯三胺整体柱。详细考察了在确定单体/固化剂比例前提下,改变聚合物混合液中聚乙二醇的含量,确定聚乙二醇含量对整体柱孔径的影响;定性分析整体柱对Cu2+吸附和解吸能力;用扫描电镜观察整体柱的孔隙形态。结果证明:当单体/固化剂为75:25时,聚乙二醇含量为70%,聚乙二醇分子量为1000时,所制备的整体柱具有很好的稳定性和吸附性能。

【Abstract】: This research prepared epoxy resin-based polymer monolithic column in 1cm×10cm . glass tube, using epoxy resin as monomer, PEG as poregen, riamine as curing agent. In the certain proportion of monomer and curing agent, the effect of the amount of PEG in the mixture on the properties of monolithic columns was researched. The adsorption and desorption of Cu2+ on the monoliths were studied qualitatively. The structure of pores was recorded by SEM. The results show that the prepared monolithic columns have good stability and adsorption capacity.
