摘要：Disclosed are methods of custom stabilization of the hydrogen peroxide used in the safe in-situ treatment of soil and groundwater. In one embodiment, disclosed is a method of in-situ chemical oxidation treatment of soil and/or groundwater wherein the hydrogen peroxide has been stabilized with carboxylate salt (e.g., sodium citrate, sodium malonate, or sodium phytate). Procedurally, chemical daylighting is avoided by: (a) mixing a batch of aqueous hydrogen peroxide solution with a carboxylate salt; (b) injecting the solution into a subterranean location; (c) allowing iron that is naturally present in the in-situ environment to mix with the solution; (d) controlling the subsurface pressure and temperature within the in-situ environment; (e) manipulating the concentration of carboxylate salt in the remainder of the hydrogen peroxide batch (as necessary), wherein the concentration of carboxylate salt defines the life-span of the hydrogen peroxide, and helps to control the subsurface reaction and minimize the possibility of chemical daylighting

主权项：1. A method of in-situ chemical oxidation comprising the steps of: (a) mixing an aqueous hydrogen peroxide solution with a carboxylate salt; (b) injecting a portion of the solution into a subsurface in-situ environment; (c) allowing iron that is present in the in-situ environment to catalyze the hydrogen peroxide in the solution; and, (d) measuring or observing a condition in the in-situ environment.
