Nanoscale zero-valent iron coated with carboxymethyl cellulose was used to remove 210Pb(II) from aqueous solution. The effects on removal result of coated NZVI/CMC concentration, solution pH value, initial 210Pb(II) radioactivity, and contact time were investigated. The characterization of coated NZVI/CMC before and after reaction was analyzed by SEM and XRD. The results show that the removal rate or absorption capacity reaches 99.25% with the pH value of 5.5, the initial 210Pb radioactivity of 2.354×103 Bq?L−1, the coated NZVI/CMC concentration of 0.8 g?L−1, and the contact time of 60 min. Great changes occur to coated NZVI/CMC has after reaction, and the hammer throw reticular structure turns to lamellar structure. Coated NZVI/CMC still has rather good removal effects on 210Pb(II) in aqueous solution.Cited
