Abstract Thiocyanate selective electrode has been made by using Cu Me Sal 2dpt II as aneutral ionophore in the PVC membrane The electrode possesses the advantages of verywide range of concentration to thiocyanate from 1 0 10 5 to 1 0 10 1 M low detection limit 8 1 10 6 M Low response time 15 sec wide pH independent range 3 5 10 5 and specially good selectivity over the wide variety of other anions The proposed electrodewas used for the determination of thiocyanate in the smoker and non smoker salivasamples A PVC membrane with 4 hydroxy salophen as an ionophore along with sodiumtetraphenyl borate NaTPB as an anion excluder and dibutyl phthalate as a solventmediator in the ratio of 28 7 3 3 63 2 4 7 w w PVC NaTPB DBP Ionophore exhibitsgood properties with a Nernstian response of 30 1 1 0 mV per decade for Cd II Theelectrode has wide working concentration range of 1 0 10 6 1 0 10 1 M Cd II Thelimit of detection is 8 4 10 7 M Cd II It has a fast response time of 20 s and the electrodecan be used in the pH range from 2 8 to 8 1 The proposed electrode has been used fordetermination of Cd II ion in water samples
