| Abstract: | Chemiluminescent systems of luminol are used to design and improve methods for the direct express evaluation of the content of chromium and nickel in corrosive media of stainless steels. By these methods, we can determine nanogram amounts of chromium and nickel in the presence of greater amounts of iron and other components of corrosive media. The methods were approved while testing corrosion of 40KhN steel in a 3% NaCl aqueous solution.
