- •
SEM, XRD, FT-IR were used to characterize modified-nZVI.
- •
APAM modification made nZVI aggregate aggressively in water.
- •
CMC-modified nZVI had better colloidal stability.
- •
nZVI modified by APAM and CMC had the slow oxidation rate.
- •
The Ni2+ removal efficiency with nZVI decreased after CMC modification.
