Performance characteristics and regeneration of a tetraphenylboron(III) selective electrode
A tetraphenylboron (TPB)-ion-selective poly(vinyl chloride)-membrane electrode based on an ion pair complex of TPB/sup -/ with hexadecylpyridinium cation (HDP/sup +/) was prepared with dioctyl phthalate as a plasticizer. Effects of changing the ion pair percent in the membrane and pH of the test solution on the electrode potential were studied. It was found that soaking the electrode in HDP solution gives better response characteristics than those obtained from electrodes soaking in TPB solution. A method for regeneration of the exhausted electrode was proposed. The electrode was highly selective for TPB with respect to some amino acids and organic and inorganic anions. TPB was determined successfully by potentiometric titration with standard HDP solution when using the investigated electrode as the sensor.
