Description:

In-situ, immobilization of metal contaminates in soil systems shows great potential as a cost-effective and environmemtally sound remediation technique. Pb contaminated soils are typically removed from site and replaced with clean soil at great costs. However, innovative technologies for sequestering Pb in-situ have been proposed and studied. For an immobilization remediation method to be effective, not only must it be capable of sequestering most of the contaminant, but it must also be successful in retaining the metal for the long-term. The objectives of this research were to examine the kinetics and mechanisms of the formation and dissolution of chloropyromorphite, a Pb immobilization endpoint, as influenced by aging time and dissolution agent pH to provide a better understanding of Pb sequestration in soil environments.
