Abstract
SODIUM thiosulfate has a strong effect on the corrosion of …….copper in salt water. It promotes the anodic dissolution of copper, while the partial cathodic reaction is not affected. It also shifts the free corrosion potential in the active direction by hundreds of mV and causes extensive corrosion of the metal. The results are substantiated with SEM, EDS and XPS measurements. A mechanism is proposed to start with adsorption of thiosulfate ions on the copper surface followed by a corrosion reaction producing copper sulfide and hydrosulfite ions.
