Claim:
A portable apparatus for decontaminating a liquid containing impurities, comprising a longitudinally extending iodine release section formed from an outer shell of a metal or a polymer other than nylon and an inner shell formed from a nylon iodophor having such quantities of bound iodine that, when contacted by said impure liquid, at least some of said bound iodine is released from said iodophor into said liquid in an amount that destroys impurities, said outer release shell and said inner release shell extending along a major portion of the length of said release section, and a longitudinally extending iodine recapture section positioned after said iodine release section to receive liquid therefrom, said recapture section being formed from an outer shell of metal or a polymer other than nylon and an inner shell formed from a nylon polymer having none or so little bound iodine that it will complex with iodine in liquid from said iodine release section to recapture and remove iodine from said liquid, said outer recapture shell and said inner recapture shell extending along a major portion of the length of said recapture section, said release and recapture sections being joined together so that they can be separated for cleaning or replacement.
