摘要：
We studied the main electrode functions of carbon paste electrodes (CPEs) modified with 0-20% of dithiooxamidated polysiloxane with respect to palladium(II). The conditions for the potentiometric titration of palladium(II) using modified CPEs as indicator electrodes were selected, namely, pH 1-2, solutions of EDTA and potassium iodide as the titrants; and modifier concentration is 0, 5, and 10%. A procedure was developed for determining palladium(II) in aqueous solutions. The procedure was tested using a GSO solution of palladium(II) and an industrially produced activator Pd-600.
