Abstract

Abstract

Nanoscale zero-valent iron(NZVI) was synthesized in aqueous solutions by reduction of Fe³⁺with KBH₄.Removal of U(Ⅵ) by NZVI was investigated to understand the effect of dosages of NZVI,pH value of solution,initial concentrations of U(Ⅵ) and contact time.The results showed that:NZVI has very good removal effect on U(Ⅵ),and when pH value of solution is 5.5,the initial concentration of U(Ⅵ) is 45 mg/L,the dosage of NZVI is 1.0 g/L,the contact time is 2.5 h,the removal rate and adsorption capacity reached 98.98% and 27.22 mg·g^-1 respectively.
