离子选择性电极的响应机理的报道较多,目前仍在进一步探讨中,但是采用示踪法者甚少。该法虽然难度较大。却具有直观和灵敏度高等优点。Thoma等采用~(42)K~+和~(36)Cl~-示踪法,对钾电极的离子传递机理进行了电渗析和扩散研究,结果表明钾离子和氯离子皆进入膜相中。Craggs、Jaber、Doyle、Moody和Thomas等经长时间的示踪试验,研究了~(45)Ca、~(36)Cl~-、~(89)Sr、~(133)Ba在由钙电极膜和钡电极膜分别组成的电池中的迁移和扩散特性,指出钡
Ion-selective electrode response mechanism reported more, is still under further investigation, but few use of tracer method. Although the law is more difficult. But has the advantages of intuitive and high sensitivity. Thoma et al investigated the ion transport mechanism of potassium electrode by electrodialysis and diffusion using ~ (42) K ~ + and ~ (36) Cl ~ - tracing methods. The results showed that both potassium and chloride ions entered the membrane phase. Craggs, Jaber, Doyle, Moody and Thomas et al. Studied the effect of ~ (45) And barium electrode membrane respectively composed of the battery migration and diffusion characteristics, barium
