摘要：

The determination of gold by the application of electrodes modified with anion exchangers is considered. Particular attention is paid to investigating the capability of these electrodes to determine gold(III) in the presence of copper(II). Electrodes modified with a film of poly(4-vinyl-pyridine) or either chemisorbed electrochemically generated were investigated. It was found that copper(II) caused little or no interference in chloride media. However, copper(II) cyanide complexes interfered with the determination of gold cyanide solutions.
