Abstract

A metal hydroxide complex has a formula Me(OH)4*A*nH2O or MeO2*A*nH2O. Preferred complexes are formed in an alkaline medium, and particularly especially preferred anions include cyanide and cyanide gold complexes. Contemplated complexes are formed on a metal hydroxide (e.g., hydrated zirconium, hafnium, and titanium hydroxide), which may be disposed in a porous container. Consequently, contemplated compounds may be used in methods of reducing the concentration of an anion in an alkaline medium.
