本支研究了国产聚苯乙烯磺酸型树脂(凝胶型)的络合淋洗色层对三价镅、锔、铕、钆的相互分离,淋洗剂采用α-羟基异丁酸。为流程和分析提供了分离方法。工作着重研究阳离子交换树脂交联度与温度如何通过分离系数β和塔板高度H对总的分离效果R_2起影响的,从中得出实际分离的最佳条件。实验结果与非平衡理论预计的结果相符合。又初步作了流速的影响。最后根据选定的分离条件和镅与锔的分离要求,选用一定的柱高进行分离,分离结果与要求相符合。同时还测定了本法对裂变产物、钚和镎的净化系数。
This study studied the domestic polystyrene sulfonic acid resin (gel type) of the complexation of the color layer of trivalent 镅, 锔, europium, gadolinium mutual separation, eluent using α-hydroxyisobutyric acid. Provides a separation method for processes and analyzes. The work focuses on how the degree of crosslinking and the temperature of the cation exchange resin influence the overall separation effect, R 2, by the separation coefficient, β, and the height of the tray, from which the optimal conditions for actual separation are derived. The experimental results are consistent with the predicted results of non-equilibrium theory. Also made a preliminary effect of the flow rate. Finally, according to the separation conditions selected and 镅 and 锔 separation requirements, the choice of a certain column height separation, the separation results in line with the requirements. At the same time, the method of determining the purification coefficient of fission products, plutonium and plutonium was also determined.
