Abstract (en)

[origin: WO2020128139A1] The disclosure relates to a material, a system and a method for collecting metals from an aqueous solution. The material comprises porous silicon structure and a metal binding ligand covalently bonded to a surface of the porous silicon structure. The system comprises material disclosed. In the method, the material or the system is contacted with an aqueous solution that contains metals, and the metal binding ligands of the material or the system interact with at least part of the metals contained in the aqueous solution, thus causing at least part of the metals to be collected by the material or the system. Metals collected by the material or the system may be qualified and/or quantified using an analytical process or instrument. Quantification of the metals collected may be used for analysis of the metal concentrations of the aqueous solution contacted with the material or the system.
