C.E.R.E.S. Ferrous Sulfate Heptahydate and Monohydrate
Ferrous Sulfate – Chemistry for heavy metals sequestration and stabilization or Chemical Reduction
Ferrous Sulfate has been used for chromium remediation in the same way that calcium polysulfide has for some decades. It is sometimes a component of MTS® blended chemistries for multi-metal contaminated soils and sold as is (Ferrous Sulfate) to customers who wish to use it on their own. We source only the best available chemistries from trusted manufacturers for environmental applications and with low impurities and HIGH reactivity. We provide reliable and high quality chemical reagents for Heavy Metals Sequestration and Stabilization, and chemical reduction reagents for use in Soil and Groundwater Remediation applications.

Soil Remediation Applications:
Sequestration of heavy metal impacted soil and groundwater Remediation is a remedial technology that has been employed for many years around the world by highly specialized remediation engineers who understand the chemistry well and its application.
Sequestration is a process where chemical reagents like Metals Treatment Solution (i.e. MTS®) are applied or injected into soil or groundwater, industrial waste or substrate to form a stable and insoluble precipitate resulting in reduced leachability of the target heavy metals.Heavy metal sequestration chemically binds metal ions in the free liquids and immobilizes them within the soil / substrate thereby reducing their solubility through the chemical reaction. The physical characteristics of the sequestrated or “stabilized” contaminated material is not changed by this process with respect to geo technical properties for redevelopment. It also does not interfere with biological systems or native biota if shallow enough to be in the root zone.
