Triprolidine hydrochloride (TpCl) ion-selective carbon paste electrodes were constructed using Tp-TPB/Tp-CoN and Tp-TPB/Tp-PTA as ion-exchangers. The two electrodes revealed Nernstian responses with slopes of 58.4 and 58.1 mV decade Γ1 at 25 Β°C in the ranges 6 β’ 10 Γ6 -1 β’ 10 Γ2 and 2 β’ 10 Γ5 -1 β’ 1
