摘要

研究了241Am3+离子在磺酸聚苯乙烯型离子交换膜中的扩散。使用Agfa-Gevaert光乳剂和塑料核径迹检测器进行定量显微放射自显影,确定膜内离子扩散浓度分布。比较了离子浓度谱图的扩散系数和两种不同方法的结果。

Comparative study of the ion transport process in a membrane system by quantitative autoradiography, using photoemulsion and plastic track detector

The diffusion of 241Am3+ ions in a sulphonic acid polystyrene type ion-exchange membrane has been studied. Ion diffusion-concentration profiles within the membrane is determined using quantitative microautoradiography performed with Agfa-Gevaert photoemulsions and plastic nuclear track detectors. The diffusion coefficients derived from the radiograms of the ion-concentration profiles and the results obtained by the two different methods are compared.
