A zinc-selective electrode with a low detection limit and its use in the analysis of environmental samples

摘要

The analytical characteristics of a tetrathiocyanozincate ion-selective film electrode were studied. The electrode membrane was based on the specially synthesized highly lipophilic ([((CH_3)_3)N(C_(43)H_(79)O_3)])_2Zn(SCN)_4 ion exchanger served as an ionophore. It was shown that this electrode can be used for deterniining zine(H) in environmental samples at the level lower than its maximum permissible concentration (MPC).
