Title:
ADSORBENT
Document Type and Number:
WIPO Patent Application WO/1989/000885
Kind Code:
A1
Abstract:
An adsorbent is prepared by mixing at least one member selected from a first group consisting of metal oxides and metal compounds capable of partly or wholly forming metal oxides when heated in an oxygen-containing atmosphere with at least one member selected from a second group consisting of metal sulfides and metal compounds capable of partly or wholly forming metal sulfides when heated in an oxygen-containing atmosphere, and heating the mixture in an oxygen-containing atmosphere. This adsorbent has a remarkably high capacity of adsorbing heavy metals such as uranium. This adsorbent, which is easy to handle and can be produced with ease, enables recovery of uranium from sea water on an industrial scale because of its remarkably high adsorbing ability.
