Title:
METAL ADSORBENT CONTAINING CHELATING POLYMER
Document Type and Number:
WIPO Patent Application WO/2010/122954
Kind Code:
A1
Abstract:
A metal adsorbent which can adsorb a wide variety of metals, can conform to various uses, and adsorbs metals in large amounts. Metal adsorbents in various forms, which have the property of highly efficiently adsorbing metals, are produced by (a) a method in which a polyamine polymer is chemically bonded and affixed to a porous support, (b) a method in which a polyamine polymer is incorporated into a solution of a raw material for fibers and the mixture is formed into fibers by wet spinning or dry spinning, and (c) a method in which a polyamine polymer is incorporated into a solution of a film-forming polymer and the mixture is formed into a film by a method of film formation from solution.
