Silver(I) ion selective PVC membrane based on bis-pyridine tetramide macrocycle.
A PVC membrane based on bis-pyridine tetramide macrocycle exhibits a good response for silver ion over a wide concentration range (1.0x10(-1)-4.0x10(-5) mol l(-1)). The electrode has a relatively fast response time and can be used for more than 5 months without observing any divergence. High selectivity for Ag(+) ions over that of Na(+), K(+), Ca(2+), Sr(2+), Pb(2+) and Hg(2+) have been observed.
