Abstract
Methods, systems, and compositions related to the recycling and/or recovery of activating materials from activated aluminum are disclosed. In one embodiment, an aqueous solution's composition may be controlled to maintain aluminum ions dissolved in solution during reaction of an activated aluminum. In another embodiment, aluminum hydroxide containing the activating materials may be dissolved into an aqueous solution to isolate the activating materials.
Claims9
A method of reacting an activated aluminum, the method comprising:
- exposing the activated aluminum to an aqueous solution, wherein the activated aluminum comprises aluminum combined with gallium and/or indium;
- reacting the aluminum in the activated aluminum with water in the aqueous solution to generate hydrogen and aluminum ions;
- and
- maintaining the aluminum ions dissolved in the aqueous solution during the reaction.
