On August 1, 2013, Gezerman, A. O.; Corbacioglu, B. D. published an article.COA of Formula: C5H5NO3S The title of the article was Iron(II) acetylacetonate containing brightener and sulphur containing carrier in nickel plating. And the article contained the following:
The effects of an Fe(II) acetylacetonate containing brightening agent and a carrier on color and mech. properties of Ni plating were studied to determine optimal electroplating process parameters. The brightening agent contained metasulfobenzaldehyde, pyridine-3-sulfonic acid, p-vinylbenzenesulfonic acid, o-benzoylsulfonamide, Na saccharine and Fe(II) acetylacetonate. The carrier comprised Na saccharine and Na allyl sulfonate in H2O. Plating color was analyzed by visible region spectrophotometry at 350 nm under 6500 K illumination (CIE Standard Illuminant D65). Electron microscopy confirmed that carrier facilitated Ni deposition onto the surface and increased cohesion, thus allowing complete coverage. Also, brightening agent increased the bath pH, while carrier did not. In bending experiments on a coated plate, brightening agent increased H embrittlement, although desired decorative appearance was obtained. Finally, the optimum concentrations of carrier and brightening agent are 12 and 0·4 g L-1, resp. The experimental process involved the reaction of Pyridine-3-sulfonic acid(cas: 636-73-7).COA of Formula: C5H5NO3S
