Mercury - Nobel Metals Filters
| View subcategories tree |
| The effluents of many industrial processes as well as surface water and groundwater from historically polluted sites often contain unacceptably high levels of Mercury and other toxic trace metals. Although inorganic Hg itself is not bioaccumulative it is readily converted to methyl mercury in the ambient environment and so should be removed before discharge. The U.S. EPA has identified mercury-contaminated groundwater and surface water as areas of particular concern and has emphasized development of innovative robust extraction technologies.
These filter use a special macroporous cation exchange resin with thiouronium functional groups. This resin has chelating properties for mercury and for noble metals when they are present as free cations. |
