Abstract
An apparatus and method for removing mercury, and in particular elemental mercury, from a fluid stream by exposing the fluid stream to a polyethersulfone surface onto which has been loaded elemental iodine. Elemental iodine is loaded onto the polyethersulfone surface by immersing the polyethersulfone substrate in an iodine/ethanol solution, then removing the substrate from the iodine/ethanol solution and rinsing in ethanol.
