Abstract
A method for pollutants using an iron-impregnated, carbon-coated silica sand with the iron containing between to and 16 percent silicon. The invention provides an improved method for performing remeditation of pollutants by dissolved metal reactions while minimizing interferences caused by oxide fouling from oxygen in the water or in the atmosphere. The invention further provides an inexpensive media with high surface area for adsorptive fixation and reductive treatment that yields higher than anticipated reaction kinetics utilizing only low concentrations of iron in the media.
