The performance of octahydroxycalix [4] arene derivative used as a neutral carrier for silver
polymeric membrane electrode was studied. The sensor gave a good Nernstian response of
58±1 mV per decade for silver ion in the activity range 3.3× 10-6 to 3.3× 10-2 M Ag+. The
limit of detection reached 2.1× 10-6 M Ag+ and exhibited high selectivity for silver ion
against the alkali, alkaline earth and transition metal ions. The sensor can be used in wide
pH range from 1.5 to 6.5. The response time of the sensor is less than 20 s. The ...
