Amperometric determination of palladium with 2-(o-Hydroxyphenyl) Benzoxazole

Summary A method for the amperometric determination of palladium is presented, which involves the formation of a palladium-2-(o-hydroxyphenyl) benzoxazole inter complex salt. The method is primarily recommended for the accurate determination of palladium in solutions containing only traces of other platinum elements. Of the several diverse ions studied, only iridium interfered seriously with the determination of palladium; however, this element is easily removed from palladium according to the standard procedure². The data obtained in the amperometric investigation of the palladium-2-(o-hydroxyphenyl) benzoxazole interaction were in agreement with the results obtained in the gravimetric study of the same reaction⁷.
