Abstract

Methods and compositions are described for preparing metal salts and selectively separating metals from substrates and other metals. The methods can include a thionyl reagent that reacts with a metal in a solution to produce a metal salt. The reaction can be controlled by varying reagents and conditions such that the method can be used to selectively separate one or more metals from another metal or from a substrate. The method can also be used for removing metals from a surface. Compositions produced by the method are also described.
