Вплив карбоксиметилцелюлози на електрохімічну та корозійну поведінку заліза у сірчанокислих електролітах
Ю.П. Вишневська, Д.А. Ткаленко
Abstract
Addition of carboxymethylcellulose to sulfate electrolytes leads to a
decrease of the corrosive destruction rate of iron (steel). It is due to the
formation of a barrier layer on the iron electrode surface. Such a layer
consists of little soluble products of co-operation of
carboxymethylcellulose with iron cations, which appear near the
electrode/electrolyte interface. A ground of the thesis that the formation
of protective layers is conditioned in many cases by the co-operating of
organic inhibitors with cations of dissolved metals is brought. In
accordance with such a supposition at the choice of organic inhibitors, it
is necessary to take into account the stability constant of the appearing
metalorganic compounds (complexes) and their solubility in the examined
environment.
