Abstract: The electrode is instrumented by p.v.c as membrane and the phosphate as ac tive.We have tested the electrode natural capacity,the pre scribed minimumis 10 -5 mol /Land the selectivity coefficie nt to the monovalent and bivalent melationis lower than0.1.It is a kind of the convenient andspee dy determination tool.

Key words: Calciumion electrode , Electromotive force , Selectivity coefficient
