Radiotracer studies with (133)Ba, (45)Ca and (36)Cl are reported for PVC matrix membranes containing 2-nitrophenyl phenyl ether and the tetraphenylborate of a barium (or calcium) complex with a nonylphenoxypoly(ethyleneoxy)ethanol (NP), Antarox CO880. The results show that there is very limited permeation of radioactive barium and calcium ions through the membrane systems. However, the continued uptake (with time) of radioactive barium ions by the membranes (the uptake of calcium ion is less) suggests that in relation to selective electrode response the stabilization of ions by the NP ligand within the membrane is important in addition to the simple availability of membrane pathways for primary-ion transport through the membrane. Permselectivity to counter-ions is indicated by the non-permeation of radioactive chloride ions.
报道了用(133)Ba、(45)Ca和(36)Cl进行的放射性示踪研究，研究对象是含有2-硝基苯基苯基醚以及钡（或钙）与壬基苯氧基聚（乙氧基）乙醇（NP，安塔罗克斯CO880）形成的配合物的四苯基硼酸盐的聚氯乙烯基质膜。结果表明，放射性钡离子和钙离子透过膜系统的渗透非常有限。然而，膜对放射性钡离子的持续吸收（随时间）（对钙离子的吸收较少）表明，就选择性电极响应而言，除了膜中存在用于初级离子通过膜传输的简单通道外，NP配体在膜内对离子的稳定作用也很重要。放射性氯离子不渗透表明了对抗衡离子的选择透过性。
