INTEROX® HYDROGEN PEROXIDE
FOR SOIL REMEDIATION
INTRODUCTION
®
INTEROX Hydrogen Peroxide is an environmentally-compatible powerful oxidizing agent that is used in a variety of
technologies to oxidize a large number of contaminants. Injection of very dilute concentrations (0.5 – 6% by weight) of
®
INTEROX Hydrogen Peroxide is also suitable for enhanced aerobic bioremediation.

* Active oxygen is the amount of oxygen available for oxidation. Every molecule of hydrogen peroxide provides one
active oxygen.
CHEMICAL PROPERTIES
®
As supplied, INTEROX Hydrogen Peroxide decomposition is slow (<1%/yr) with no temperature rise, but it is
accelerated by heat and decomposition catalysts, such as transition metals and their compounds, strong alkalis, and
organics.
Hydrogen Peroxide decomposes exothermally to water and oxygen with no toxic residues.
H2O2  H2O + ½ O2 + heat
APPLICATIONS
In-Situ Chemical Oxidation
®
INTEROX Hydrogen Peroxide is an oxidant commonly employed to degrade many toxic organic compounds. There
®
are several approaches for the use of INTEROX Hydrogen Peroxide in soil and groundwater remediation. These
mostly involve the generation of the hydroxyl free radical, which is a short lived but very powerful oxidizer.
• Fenton’s Reagent involves the combination of hydrogen peroxide with an iron salt and an acid
to generate the hydroxyl free radical.
®
• Modified Fenton’s Chemistry is based on the use of INTEROX Hydrogen Peroxide with an iron
salt or chelate without acid to generate the hydroxyl free radical.
®
• Use of a combination of ozone or ultra-violet radiation and INTEROX Hydrogen Peroxide to generate the
free hydroxyl radical.
®
• INTEROX Hydrogen Peroxide can be injected in the soil with no other additives for a slower direct
oxidation approach to remediation.

Technical Data Sheet
BIOREMEDIATION
®
INTEROX Hydrogen Peroxide can also be used to enhance aerobic biodegradation by acting as an oxygen source.
The product generates oxygen in situ when in contact with contaminants, transition metals and microbial enzymes.
Concentrations used for enhanced bioremediation are between 0.5-6% by weight.
AVAILABILITY
®
INTEROX Technical Grade hydrogen peroxide is sold in concentrations of 35% and 50% and is available in bulk
truck or railcar quantities from Solvay Chemicals La Porte, Texas and Longview, Washington plants. Tote and drum
quantities of hydrogen peroxide are available from Solvay Chemicals distributors.
For more information, or to place an order, please contact Solvay Chemicals Customer Service at 1-800-443-2785.
STORAGE AND HANDLING
Store hydrogen peroxide in the original vented container, upright, in a cool, ventilated area where it is protected from
damage, or in bulk storage tanks made from approved materials of construction.
Do not store other chemicals, fuels, or combustible materials near hydrogen peroxide.
Never return unused hydrogen peroxide to the storage container.
When empty, rinse all peroxide containers thoroughly with clean water before discarding.
Use only approved material for pumps, valves, piping, and hoses.
SAFETY
Persons working with hydrogen peroxide should be familiar with personal protective equipment, first aid measures
and the proper safety and handling procedures. Consult the Safety Data Sheet (SDS) for appropriate information.
Prevent accidental decomposition by keeping the product free of contaminants.
Prevent fires by avoiding accidental spills. Water is the preferred method for extinguishing fires in which hydrogen
peroxide is present.
Spills and leaks should be contained, diluted with copious amounts of water and disposed of in compliance with local
regulations.
Hydrogen peroxide storage or handling areas should be equipped with a safety shower, an eyewash station, and a
water hose.
FIRST AID
In case of product splashing into the eyes and face, treat eyes first.
Eye contact: Flush eyes immediately with water for at least 15 minutes. Call a physician.
Skin contact: Immediately flush skin with water while removing contaminated clothing and shoes. Call a physician if
irritation persists.
Inhalation: Remove the victim from the contaminated area to fresh air. Call a physician in case of respiratory
symptoms.
