Dibazol ion-selective electrodes.
Liquid-membrane and polyvinylchloride membrane dibazol ion-selective electrodes have been developed. They are based on ion-pair complexes of dibazol with dicyclohexylnaphthalene sulphonate, diisopentylnaphthalene sulphonate, diisobutylnaphthalene sulphonate and tetraphenylborate. The electrodes show near-Nernstian response for dibazol in the concentration range of ca 10(-5)-10(-2) M in the pH range 3-7. The electrodes can be used in the potentiometric determination of dibazol.
