Porous hollow fiber membrane having chelate formability and method for recovery of germanium oxide using the porous hollow fiber membrane |
| abstract |
There are provided a porous hollow fiber membrane capable of economically and efficiently recovering germanium which has heretofore been entirely disposed as a waste, and a method for recovery of germanium oxide using such a porous hollow fiber membrane.The porous hollow fiber membrane of the present invention is characterized by being obtained by reacting the residue of an epoxy group-containing compound subjected to irradiation-induced graft polymerization on a polyethylene-made porous hollow fiber membrane, with a compound capable of reacting with said reside to give a residue containing a structure represented by the following formula:(wherein R1 and R2 are a hydrogen atom or a lower alkyl group) or the following formula:and the method for recovery of germanium oxide according to the present invention is characterized by contacting an aqueous germanium oxide solution with the above porous hollow fiber membrane having chelate formability, to allow the porous hollow fiber membrane having chelate formability, to capture the germanium oxide contained in the aqueous solution, and then dissolving the captured germanium oxide into an acidic solution. |
