| 摘 要： | 最近几年已报道了几种锂离子选择性电极.本文作者曾研制了以苯基膦酸二辛酯(DOPP)为溶剂,四苯硼酸盐为活性物质的PVC膜锂离子选择电极.本文在此基础上研制了锂离子选择性微电极,比较了以四苯硼酸钾(KTPB)及四苯硼酸钠(NaTPB)为活性物质的锂微电极的性能.同时考察了微电极在细胞内液、血清及生理盐液中对锂离子的响应特性.

| Abstract: | A new PVC lithium ion-selective microelectrode based on potassium tetraphenylborate(KTPB) or sodium tetraphenylborate (NaTPB) and plasticized by di-(n-octyl)-phenylphos-phonate (DOPP) has been constructed. The microelectrode based on KTPB has lower detec-tion limit and better selectivity characteristics for bivalent ions, but the microelcetrodebased on NaTPB has lower membrane resistance. The response characteristics of microelect-rode for different concentrations in Li has been examined experimenetally in synthetic in-tracellular solution,serum and physiological saline. |
