Chemical and electrochemical approach to find out the effect of soluble sulfonated polystyrene polymer inhibitor with 0.5 M HCl mixtures on the interface of low carbon steel surface

The author has focused on the corrosive effect of 0.14% carbon steel in occurrence several amounts soluble Sulfonated Polystyrene (SPS) and was found to be best efficient soft iron exterior at 100ppm concentration 0.5M hydrochloric acid assortment 298K heat during 3h time this paper. examination performed by studying weight loss mild varying different parameters like mixture concentration, time, solution temperature. efficiency SPS observed rise with an increase 91.90% inhibitor solution. mechanism physical adsorption studied initiation permitted dynamics for reaction altitude extracted taking place towards sample endothermic, impulsive dependable through Langmuir isotherm adsorption. Anodic cathodic both type nature using potentiodynamic polarization method. AFM analysis used do surface protective film under varied settings, polymer proven more suited metal exterior.
