Welcome to Redox Solutions
Redox Solutions a an Indianapolis-based chemical manufacturer specializing in the production of “mackinawite” structured iron sulfide based reagents.
Markets we serve
Removal Mechanisms of Mackinawite
- Dissolution / Precipitation
- Occlusion / Mixed crystal formation / Physical entrapment
- Surface adsorption
- Electron Transfer / Electron “Hopping”
What makes Mackinawite Structured Iron Sulfide based Reagents Unique?
- The ability to remove multiple metals in multiple valence states.
- The ability to simultaneously reduce Cr(6+) to Cr(3+) and bind the Cr(3+) into the mineral structure, even in highly alkaline waste(s).
- Extremely effective on waste(s) containing oxidized and elemental mercury (Hg), and/or uranium (U).
- Effective on mixed-organic (chlorinated) / inorganic wastes streams.
Our Novel Mackinawite Based Reagents are:
- Highly distorted crystalline structured allowing for optimal reactivity.
- Stable and less prone to oxidation prior to application either in-situ or ex-situ.
- Synthesized abiotically at our chemical plant located in Indianapolis, Indiana with particle sizes ranging from sub-micron to 200-micron.
- Formulated with excess compounds (e.g. sulfide, iron, aluminum) depending upon on site conditions or the “contaminants of concern” (COC).
Biotic vs. Abiotic Iron Sulfide
To date, in-situ treatment of heavy metal impacted soils and/or groundwater through biotic iron sulfide formation has met with varying levels of success. Simply, Redox Solutions abiotically synthesized products eliminate the unknown factors of biotic iron sulfide formation.
