Abstract: An adsorbent is disclosed which uses an iron-containing metal oxide as an adsorbent for removing heavy elements from contaminated waters and method for the use of the same. The bed includes a non-stoichiometric ferrous oxide Fe1-xO, which is structurally in a Wustite crystal phase form having the rock salt, face-centered cubic lattice.

Abstract: The invention is a method for producing a cast cermet anode for metal oxide electrolytic reduction by feeding metallic iron and metallic nickel in solid form to an oxidizing reactor; melting and oxidizing the iron and nickel and forming molten nickel ferrite; mixing the molten nickel ferrite with a base metal of high electrical conductivity such as nickel, copper, silver, or alloys thereof in a holding vessel such as ladle or tundish, and casting the mixture into a mold to form a near net shape of the desired anode. Apparatus for carrying out the method, and the resulting product are also disclosed.

Abstract: The invention is a method for producing a cast ceramic anode for metal oxide electrolytic reduction by feeding metallic iron and metallic nickel in solid form to an oxidizing reactor; melting and oxidizing the iron and nickel and forming molten nickel ferrite; mixing the molten nickel ferrite with dopant in a holding vessel such as ladle or tundish to increase electrical conductivity of the mixture, and casting the mixture into a mold to form a near net shape of the desired anode. Apparatus for carrying out the method, and the resulting product are also disclosed.
