Title:

METAL ION ADSORBENT

Document Type and Number:

WIPO Patent Application WO/2006/013864

Kind Code:

A1

Abstract:

A metal ion adsorptive sheet carrying a photoresponsive metal ion adsorbent material that ensures easy handling, excelling in the efficiency of contact between metal ions contained in an aqueous solution and the photoresponsive metal ion adsorbent material to thereby realize efficient light receiving, and that facilitates discrimination of a color change at adsorption/desorption, permitting repeated use for a prolonged period of time, and that permits taking out of desorbed metal ions from the system. There is provided a metal ion adsorptive sheet characterized in that a photoresponsive metal ion adsorbent material is borne on a base sheet.
