Patent number: 11850571Abstract: This disclosure provides polyamine sorbent compositions for the separation of metals from aqueous solutions. The polyamine sorbent compositions comprise a silica support, an aminosilane bound to the silica support, an epoxysilane bound to the silica support, and a polyamine where the polyamine is chemically tethered onto a solid silica support through via the epoxysilane. The polyamine may be further stabilized within the bulk sorbent through hydrogen bonding interactions with the aminosilane. The sorbent compositions resist leaching by H2O in an aqueous stream containing heavy oxyanion-based (and other) metals and demonstrate stability over a pH range of 2-14. The sorbent compositions are useful for the separation of metals from aqueous solutions. The cationic heavy metals are captured by the co-existing amine groups (—NH2, —NH, —N) from the polymeric network while additional metal capture capacity is derived from the introduction of a secondary silane linker.Type: GrantFiled: July 20, 2020Date of Patent: December 26, 2023Assignee: United States Department of EnergyInventors: McMahan L Gray, Brian W.
