Abstract

The present invention provides systems and methods for removing an oxidizable target contaminant from a fluid, and methods for their use. In embodiments, these systems and methods include an oxidizing agent, wherein adding the oxidizing agent to the oxidizable target contaminant forms an oxidized species that precipitates as an insoluble precipitate in the fluid; a substrate that forms a removable complex with the insoluble precipitate, thereby sequestering the oxidizable contaminant, and a removal system for removing the removable complex from the fluid.
