摘要：

Three synthetic hematite (SH) materials as iron oxides nanofibers were prepared and applied for the removal of Cr-51 and radioiodine (I-131) as anions associated with nuclear industry technology. The results exhibited that 70% of Cr(VI) and 90% of I-131 were removed from aqueous solution using the SH1 adsorbent. In acid solutions, R % of Cr(VI) increased to > 90% with the decrease in concentration till 0.05M, while the R % of I-131 was 94 and 79% at HNO3 and HCl, respectively. It was concluded that SH1 nanofibers is promising and selective adsorbent for Cr(VI) and I-131 removal from aqueous or acid solutions.
