CHARACTERIZATION OF A NEW NEW Ag+ -SELECTIVE ELECTRODE BASED ON N3S5-THIAAZACROWN ETHER AS NEUTRAL IONOPHORE

A N3S5-azathiacrown ether has been newly synthesized in high yield. Electrode using this compound as ionophore shows high selectivity and sensitivity towards Ag+. The effect of plasticizers and ion-exchanger on the properties of electrode was also studied and detection limit of 3.8 x 10-8 M Ag+ was...
