以十六烷基三辛基氰亚金酸铵作离子交换剂制备了PVC敏感膜,并用铂丝插入0.01MKAu(CN)_2-0.01MK_3Fe(CN)_6-0.01MK_4Fe(CN)_6溶液中作内参比体系,制成Au(CN)~-_2离子选择电极,测试了电极的各种主要性能,还测试了对十七种阴离子的电位选择性系数,并对其规律进行了讨论。
A PVC sensitive membrane was prepared with cetyltrioctylammonium cyanurate as ion exchanger and inserted into the solution of 0.01M KAu (CN) _2-0.01MK_3Fe (CN) _6-0.01MK_4Fe (CN) _6 with platinum wire Internal reference system, Au (CN) ~ -_2 ion-selective electrode was fabricated. The main properties of the electrode were tested. The potential selectivity of seventeen anions was also tested and the regularity was discussed.
