| 中文摘要 | n-methylimidazolium functionalized anion exchange resin in no(3)(-) form (rno(3)) was prepared and used for adsorption of ce(iv) in nitric acid medium. the adsorption amount increased with shaking time increasing and the adsorption equilibrium was obtained within 180 min. ce(iv) was partially reduced to ce(iii) and the reduction percent of ce(iv) increased with shaking time increasing. but rno(3) was more stable than other resins due to the high resistance to oxidation. a little increase of adsorption amount was found with concentration of hno(3) increasing. however, the reduction percent of ce(iv) decreased with the increase of hno(3) concentration. the addition of nano(3) decreased the adsorption amount of ce(iv) on rno(3) due to the competitive anion exchange reaction. ce(iv) was adsorbed on rno3 in the form of ce(iv) anion nitrato-complex. rno(3) and ce(iv)-loaded rno(3) were characterized by fourier transform infrared (ft-ir) and thermogravimeric analysis (tga). ce(iv) could be easily separated from re(iii) solution by rno(3). |
