title: Analytical techniques for corrosion studies on noble metals.
abstract: The suitability of various analytical methods for studying the corrosion of gold, silver and palladium in various electrolytes has been investigated. The methods included potentiometry with ion-selective electrodes, polarography and atomic-absorption spectrophotometry. All three methods are useful for monitoring low corrosion rates by solution analysis but each has its limitations. Concentrations in the ng/ml range can be measured routinely with errors of 10% or less.
