Azodyes as corrosion inhibitors for dissolution of C-steel in hydrochloric acid solution

The effect of some mono azo dye compounds on the dissolution of carbon steel (type L-52) in 2M hydrochloric acid solution was studied using weight loss and galvanostatic polarization techniques. The inhibition efficiency was found to increase with increasing inhibitor concentration and decreasing temperatures. Inhibition was explained by formation of insoluble complex adsorbed on the metal surface. The adsorption...

Binding pattern of ferrocyphen upon interaction with cetyltrimethyl ammonium bromide in the presence of urea

Cetyltrimethylammonium bromide (CTABr) have been titrated against Ferrocyphen (Dicyano-bis-(1, 10-phenanthroline) iron II complex) in aqueous solution as a function of urea concentration which gave a sigmoidal binding isotherm. A simple method was introduced for resolution and characterization of binding set on the basis of binding capacity concept to give hill coefficient > 1.0. Hill coefficient greater than one are...
