摘要： A heterogeneous material (e.g., a metal-organic framework or “MOF”) is useful for removing heavy metals from a liquid (e.g., water). The heterogeneous material may incorporate a group 16-containing heterocycle supported on solid media. Thiophene-containing MOFs, such as ATF-1 and DUT-67, may be used to remove lead from water. It is postulated that the metal is adsorbed via non-covalent interactions. The systems and methods described herein may also be applicable to other heavy metals. Thus, the applications are not limited to drinking water purification. Instead, the systems and methods may be used for a broad variety of other applications, such as nuclear waste remediation.

摘要： A metal organic framework includes metal-containing secondary building units and perfluorinated linkers (e.g., pefluorinated arene linkers, perfluorinated heteroarene linkers, etc.). The metal may be copper, zinc, hafnium, zirconium, aluminum, gallium, or indium. A method for removing contaminants from wastewater may utilize the metal organic framework. The contaminants may include arenes.
