- •
nZVI ability to adsorb over 90% of the Sb was demonstrated.
- •
Chemical speciation study showed nZVI's ability to reduce Sb(V) to Sb(III).
- •
Sb(V) reduction/chemisorption by pristine nZVI followed pseudo first-order kinetics.
- •
Humic acid-coated nZVI adsorb Sb ~ 10 times slower than pristine nZVI.
- •
nZVI's capability to sequester Sb in contaminated soils is demonstrated.
