Adsorption of persulfide on steel that act as corrosion inhibitors in aqueous and salt environments, simulating sea water

In published scientific work presents the simulated environment in the quantum chemistry package HyperChem version 8.0.9 using semiempirical method ZINDO/1 the adsorption process of organic compounds of the class of sulphidefenols, on iron atoms (available in tested steel grade in the amount of 97%). The scientific novelty of the research is to move away from the technology cluster simulation and attracting more informative approximation to donor-acceptor interaction of organic compounds with the iron atoms. This approach, as will be shown, with high accuracy reflects the process of galvanic corrosion protection in water-salt corrosive environments, simulating sea water, by electrochemisorption test as a corrosion inhibitor organic compounds on the metal surface with the formation of complex compounds. In the research process were obtained and analyzed: the composition of the complexes (ironsulphidefenols), a graph showing the dependence of the local electrophilicity the sulfur atom, the magnitude of the protective effect (inversely proportional to corrosion rate).
