摘要：
Applicability of polyantimonic acid-polyacrylonitrile (PAA-PAN) in 60-150 mesh for removal of strontium(II) from simulated high-level liquid waste (HLLW) was investigated in this paper. The adsorption behavior of Sr(II) and other typical fission products (FPs) onto PAA-PAN was determined by using batch experiments. The results show that PAA-PAN exhibited high adsorption affinity for Sr(II) in HNO3 medium, and other FPs except for Zr, which could be eluted by H2C2O4-HNO3, were weakly adsorbed on PAA-PAN. Then, a column experiment was performed to remove Sr(II) from simulated HLLW, and it's found that Sr(II) could be effectively transferred onto the PAA-PAN column from HLLW.
