ABSTRACT:
A device is provided for removing and concentrating neutral mercury species from air and water. The device includes a nonporous polymeric membrane, preferably in the form of a flattened tube, for capturing and removing the neutral mercury species from the environment and a sequestration medium contained within the tube for transforming the neutral mercury species captured by the tube into a stabilized mercury species. The sequestration medium can comprise an acidic oxidant for transforming the neutral mercury species into a ionic soluble mercury species or a complexing agent for transforming the mercury species into a complexed soluble mercury species. The nonporous membrane can be made of a number of different synthetic polymers including polyethylene. The device is ideally suited for the passive integrative sequestration of neutral mercury species from a wide variety of environments.
