a method by which it is possible to introduce a high-density iminodiacetate (ida) group into a polyethylene microfiltration membrane without lowering the water fluxwas developed by selecting solvents for graft polymerization and subsequent chemical modification. grafting of glycidyl methacrylate (gma) onto the porous hollow fiber in a methanol solvent enhanced the swelling of the matrix and thus compensated for the decrease in pore volume subsequently, the dimethyl sulfoxide (dmso/water solvent provided a higher conversion of the produced expoxide group into the ida group the resulting ida-group-containing hollow fiber had a sufficient cobalt-binding capacity and maintained the water flux at a feasible level.
