HDEHP-大孔硅基色层树脂对Eu~（3＋）的吸附性能研究

摘要

The extraction of resin supported by the macroporous silica-based was becoming a hot research field in separation of,macromolecules and metal ions.The separation can be achieved rapidly and efficiently.Macroporous silica-based which got chemical processed by physical perfusion was prepared.Then HDEHP-macroporous silica-based resin was made.The adsorption capacity of Eu3＋ using HDEHP-macroporous silica-based resin and HDEHP-Kel-f resin was studied.The results showed that HDEHP-macroporous silica-based resin separated rapidly and had great adsorption capacity.%大孔硅基载体支持萃取树脂在分离大分子和较大半径金属离子方面前景广阔,可实现快速有效的分离。本实验通过物理灌注方法对大孔硅胶进行化学修饰制备了大孔硅基,并结合HDEHP合成了HDEHP-大孔硅基树脂。通过对比,研究了HDEHP-大孔硅基树脂和HDEHP-Kel-f树脂对Eu3＋的吸附性能。结果表明,HDEHP-大孔硅基树脂吸附速率快、吸附容量大。
