Abstract

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.

修饰碳糊电极电位法测定水溶液中的钯（II）

摘要

我们研究了碳糊电极（CPE）的主要电极功能，该碳糊电极用相对于钯（II）的0–20％的二硫代酰胺化的聚硅氧烷改性。选择了使用改性的CPE作为指示电极的电位滴定钯（II）的条件，即pH 1-2，EDTA溶液和碘化钾作为滴定剂。改性剂的浓度为0、5和10％。开发了一种测定水溶液中钯（II）的程序。使用钯（II）的GSO溶液和工业生产的活化剂Pd-600对程序进行了测试。
