将甲基丙烯酸缩水甘油酯接枝到微滤中空纤维膜上。随后，将产生的环氧基团转化为亚氨基二乙酸酯（IDA）基团。钴溶液通过亚微米直径的孔渗透穿过螯合多孔膜。渗透过程中钴离子的有效去除由所得的穿透曲线证明。此外，通过X射线微区分析（XMA）确定了钴的跨膜吸附量与流出液体积的关系
Glycidyl methacrylate was grafted onto a microfiltration hollow-fiber membrane. Subsequently, the produced epoxide group was converted into an iminodiacetate (IDA) group. The cobalt solution was permeated across the chelating porous membrane through the submicron-diameter pores. The efficient removal of cobalt ion during permeation was demonstrated by the resulting breathrough curve. Furthermore, the prove of the amount of cobalt sorbed across the membrane was determined as a function of the effluent volume by X-ray microanalysis (XMA)
