Metals Removal Technology | UniPure

Through this rapid oxidation the solubility of the iron falls from the Fe+2 curve to the Fe+3 curve shown on Figure 5. As the iron drops out of solution, it incorporates the heavy metals in a dense iron matrix as it forms. The metals are "occluded" in the iron solids due to their close association with the iron prior to its precipitation.
