Abstract

The purpose of this work was to study several substances as ionophores for PVC matrix electrodes, sensitive to the presence of Cr3+ ions. The best results showed the electrode based on N1N5-bissalicillidene-Smethylizothiocarbohydrazone ionophore. Measurements were made in different Cr3+ salt solutions, but those in Cr2(SO4)3 solutions proved to be the most successful: S = -20.2 mV / decade L.D = 1·10-4. Optimum pH range 0 to 2.
