Abstract

Abstract A process for the removal of organic contaminants from a fluid stream containing organic contaminants. The process involves dispersing a magnetically susceptible iron-carbon complex in the fluid stream, maintaining the magnetically susceptible ironcarbon complex in a dispersed condition until a substantial amount of contaminants have been adsorbed from the fluid stream, and passing the magnetically susceptible iron-carbon complex containing dispersion through a magnetic filter to separate the dispersion into a fluid stream having a reduced concentration of contaminants and an adsorbed complex containing contaminants. Regeneration of the adsorbed complex may be accomplished by heating the complex in an inert atmosphere at a temperature sufficient to desorb and vaporize the contaminants.
