Abstract
It is demonstrated that halogenated dioxin and its derivatives can be separated from polluted aqueous solutions using pervaporation technique with a nanopore membrane fabricated by heavy-ion beam irradiation. The concentration of dioxin in the sample solution was set below 1 ppm. Polyethyleneterphthalate membrane was used. The membrane was first irradiated with high energy Xe-ions of 450 MeV with a fluence of 3 x 10{sup 3} to 3 x 10{sup 9} ions/cm{sup 2} using TIARA facility of JAERI Takasaki, etched with 6 mol/l NaOH solution resulting in formation of pores with diameter ranging from several to 40 nm, followed by grafting with monomers having affinity to dioxin. Dibenzo-p-dioxin was used to obtain permeability data. Separation factor obtained were within the range from 10 to 50. (S. Ohno)
