Pitting potentials of the treated ... WebIn the same behavior the reaction between OA and CA with metal ions, donor atoms of OA and CA are oxygen (O) contain unshared electron pair, which can coordinate a metal ion. Citric acid consist of three donor atoms (O.) with unshared electron pair can coordinate a metal ion. Therefore, citric acid was considered to be tridentate ligand.
WebFeb 27, 2024 · Another cost-saving benefit of citric acid passivation is its efficiency in removing free iron from the metal’s surface with a much lower solution concentration than nitric acid. A citric acid solution is typically in the 4 to 10% range by weight. Passivation baths generally take less time than those for nitric acid, too, with production ...
