Abstract

Mesoporous silica containing amino surface groups displayed good capacity and excellent selectivity for adsorption of precious metals (i.e., Au and Ag). The adsorbed metals were recovered as high purity metal salt solution by simple acid wash and the regenerated adsorbents were reused without lost of performance.
