Abstract: The disclosure is directed to removal of metal contaminants from fluids, as well as ligand-modified filter materials useful for carrying out such methods. The filters and methods of this disclosure are particularly effective for removal of metals from liquid compositions comprising amines. Such liquid compositions with significantly reduced amounts of metals can be used in a microelectronic manufacturing process, such as liquids for removing photoresist or liquids used in etching. The ligand-modified filters, such as ligand-modified porous membranes, can be configured for use in a microelectronic manufacturing system, which can be utilized in the system as a point of use metal-removal feature for liquids entering the system.
