摘要
建立了辐照后30％TRPO-煤油体系中氢气含量的气相色谱测定方法,测定了辐照不同剂量后的萃取剂体系产生的辐解气体中氢气的含量,计算了其辐射化学产额(G值)。
A gas chromatography method for determination of the yield of hydrogen, which is generated by radioly-sis of trialkylphosphine oxide (TRPO), a new extractant, is developed. The preferred GC condition is that the temperature of column, injection, detector and filament is 50℃ , 80℃, 80℃, and 100℃, respectively. The pressure of the carrier gas before column is (2.07 - 2.76) × 105 Fa (20 - 50 psig). The yield of H2 in the gaseous radiolytic products is determined using the method. The results show that (he yield increase ilnearly with the increasing of the radiation dose. Based on this results, the radiation chemical yield (G) was calculated.
