  2. Fenton's reagent - Wikipedia

    en.wikipedia.org/wiki/Fenton's_reagent

    Fenton's reagent is a solution of hydrogen peroxide (H 2 O 2) and an iron catalyst (typically iron(II) sulfate, FeSO 4). [1] It is used to oxidize contaminants or waste water as part of an advanced oxidation process. Fenton's reagent can be used to destroy organic compounds such as trichloroethylene and tetrachloroethylene (perchloroethylene).

  3. In situ chemical oxidation - Wikipedia

    en.wikipedia.org/wiki/In_situ_chemical_oxidation

    Deep soil mixing requires specialized auger mixing equipment. In order to apply this method in-situ and in deep soil, the oxidant must be pumped to the point of mixing using a kelly bar (a piece of earth drilling equipment), or appropriate piping to the place where the soil needs to be oxidized. The soil then has to be mixed by using mixing blades.

  4. Rust converter - Wikipedia

    en.wikipedia.org/wiki/Rust_converter

    Rust converters are chemical solutions or primers that can be applied directly to an iron or iron alloy surface to convert iron oxides into a protective chemical barrier. These compounds interact with iron oxides, especially iron(III) oxide , converting them into an adherent black layer ( black oxide ) that is more resistant to moisture and ...

  5. Calcium peroxide - Wikipedia

    en.wikipedia.org/wiki/Calcium_peroxide

    In the ecological restoration industry it is used in the treatment of soils. Calcium peroxide is used in a similar manner to magnesium peroxide for environmental restoration programs. It is used to restore soil and groundwater contaminated with petroleum by the process of enhanced in-situ bioremediation. It is a minor component of some dentifrices.

  6. Iron (III) oxide-hydroxide - Wikipedia

    en.wikipedia.org/wiki/Iron(III)_oxide-hydroxide

    Lepidocrocite, the γ polymorph, is commonly encountered as rust on the inside of steel water pipes and tanks. Feroxyhyte (δ) is formed under the high pressure conditions of sea and ocean floors, being thermodynamically unstable with respect to the α polymorph (goethite) at surface conditions.

  9. Soil conditioner - Wikipedia

    en.wikipedia.org/wiki/Soil_conditioner

    In general usage, the term "soil conditioner" is often thought of as a subset of the category soil amendments (or soil improvement, soil condition), which more often is understood to include a wide range of fertilizers and non-organic materials. [1] In the context of construction soil conditioning is also called soil stabilization.
