Abstract

This invention relates to methods and compositions for removing contaminants from fluids, for example, the removal of mercury contaminants by oxidation. The compositions and methods provided herein are robust and accomplish efficient removal of contaminants from fluid streams without the need for relatively expensive activated carbon. In addition, the methods and compositions of the present invention do not pose risks to the safety of workers through the injection of highly toxic, highly corrosive elemental bromine to directly oxidize the mercury. The compositions and methods of the present invention are versatile and apply to a wide range of contaminants including, but not limited to, mercury, lead, cadmium, thallium, and hydrogen sulfides. Further, the compositions and methods contained herein are capable of efficient contaminant removal over a wide range of temperatures and pressures.
