Abstract

An epoxy-group-containing monomer, glycidyl methacrylate (GMA), was grafted onto a porous hollow-fiber membrane made of polyethylene by immersion of the electron-beam-irradiated membrane in GMA/methanol and GMA/1-butanol solution. Subsequently, the produced epoxy group of the graft chain was converted into four kinds of chelate-forming groups capable of recovering an organic germanium compound, poly-trans- [(2-carboxyethyl) germanium sesquioxide] (p.t-CEtGeO). Breakthrough curves of p.t-CEtGeO during the permeation of a p.t-CEtGeO solution through the pores of the chelating porous hollow-fiber membranes were determined to compare the adsorption capacity; the membrane prepared by the reaction of the poly-GMA chain with 2-nitrilopropanol-2-nitriloisopropanol exhibited the highest adsorption capacity of p.t-CEtGeO at 34 mg per g of the membrane. The membrane prepared in 1-butanol has 1.5-fold greater adsorption capacity than that prepared in methanol. Breakthrough curves overlapped irrespective of the residence time of the p.t-CEtGeO solution across the membrane of 1.7 to 17 sec. High-speed recovery was realized due to negligible diffusional mass-transfer resistance of p.t-CEtGeO to the chelate-forming group of the graft chain.
