ERLDevelopment of In Situ Sequential Oxidation-Reduction Technology for Subsurface Remediation
: Enhancement of Selectivity and Reactivity
- Development of reactive materials with high selectivity/reactivity & low self-decomposition characteristics for contaminants in soil/groundwater
- Development of sequential oxidation-reduction process using ZVI-based reactive materials
- Development of direct push technology combined with hydraulic fracturing for injection of reactantive materials
- Optimization and verification of the technology through field tests
Advanced chemical oxidation
- In-situ chemical oxidation using NZVI-activated persulfate
- Formation of reactive oxygen species in PS-NZVI oxidation process
- Effects of core-shell structure of NZVI on the oxidation process
- Effects of anions and dissoved organic matters on the oxidation process
- Development of PS-NZVI oxidation process coupled with electrochemical enhancement
NZVI-based remediation
- In-situ remediation of soil & groundwater contaminated by chlorinated organic pollutants
- Development of shell-modified NZVI
- Changes in core-shell structure of NZVI within remediation process
- Effects of groundwater solutes (anions, dissolved organic matters) on NZVI-based process
- Stability of NZVI in subsurface environment
