The invention relates to sulfonated aminomethylated chelate resins, to a method for producing same, to the use thereof for obtaining and purifying metals, in particular rare earth metals, from aqueous solutions and organic liquids, and for producing highly pure silicon.

Methods for the production of co-deposition products include an oxidized metal species attached to silica in the presence of oxidation means. Also provided are methods for the production of composite materials which include a substrate and the co-deposition product. Furthermore, methods for producing a multi-layered co-deposition product which include two or more layers of the co-deposition product are also described. Co-deposition products comprising an oxidized species of metal, such as oxidized silver or copper, attached to silica are also provided. In a preferred embodiment, the metal is silver, and the resulting co-deposition product provides anti-microbial, anti-fungal and/or anti-biofilm properties to materials.
