摘要：

A cobalt-selective solid-contact electrode was prepared on the basis of titanium ditelluride. The electrode exhibits the slope of the electrode function -(29 +/- 1) mV/pC and provides the determination of 1 x 10(-5)-1 x 10(-1) M cobalt(II) in the pH range 4.5-6.5. The electrode was used for the potentiometric indication of the titration end point in the determination of cobalt(II) in lanthanum-strontium cobaltite La0.5Sr0.5CoO3. The intercalant concentration range providing optimal ion-selective properties was determined.
