ABSTRACT:
In a method for removing mercury from a wastestream to produce an environmentally acceptable discharge, the wastestream is contacted with an effective amount of an adsorbent composition which includes a metal compound capable of forming an amalgam and/or a sulfide with mercury and a support. After contact, the treated wastewater is discharged amd the adsorbent composition is regenerated. A method for making the adsorbents is also provided.
