Abstract
Disclosed herein are methods and devices for removing metal cations from fluid. The method includes filtering the fluid through a membrane, which includes a polymeric substrate and a plurality of 1T/1T′—transition metal dichalcogenide (TMD) nanosheets disposed thereon. The membrane is capable of reducing the concentration of the metal cations in the fluid from about 2 parts per million (ppm) to below 10 parts per billion (ppb). Also disclosed herein is a device for removing metal cations from a fluid. The device includes the present membrane described above, in which the membrane is capable of reducing the concentration of the metal cations in the fluid from about 2 ppm to below 10 ppb.
