Radiation-chemical stability of ionic liquid [Hbet][Tf2N] has been investigated under gamma irradiation for Nd2O3 separation from simulated spent nuclear fuels. It was found that Nd2O3 dissolution decreases with increasing absorbed dose of [Hbet][Tf2N]. However, the dissolution ability of irradiated [Hbet][Tf2N] to Nd2O3 can be regenerated after washing with water. The radiolytic products of [Hbet][Tf2N] were identified by EMI–MS, and [Hbet]+ group occurred a little radiolysis during irradiation. The UV–Visible spectra shown an increase in absorption around 275 nm probably due to the radiolysis of [Hbet][Tf2N]. FTIR spectra shown little variation around 1730 cm−1 under high radiation dose.

从模拟乏核燃料中分离 Nd2O3 对离子液体 [Hbet][Tf2N] 的辐射效应

离子液体 [Hbet][Tf2N] 的辐射化学稳定性已在伽马辐射下进行了研究,用于从模拟乏核燃料中分离 Nd2O3。发现 Nd2O3 的溶解随着 [Hbet][Tf2N] 吸收剂量的增加而降低。然而,辐照后的 [Hbet][Tf2N] 对 Nd2O3 的溶解能力在用水洗涤后可以再生。[Hbet][Tf2N]的辐解产物经EMI-MS鉴定,[Hbet]+基团在辐照过程中发生少量辐解。紫外-可见光谱显示在 275 nm 附近吸收增加,这可能是由于 [Hbet][Tf2N] 的辐射分解。在高辐射剂量下,FTIR 光谱在 1730 cm-1 附近几乎没有变化。
