“…5,6 One of the most common strategies to counter this problem is the introduction of organic compounds as corrosion inhibitors to the acid solution. 1,7,8 The adsorption of organic inhibitor molecules on the metal surface prevents direct contact between the metal surface and acid solution. However, most of the organic-based corrosion inhibitors are expensive and toxic to human beings and environment.…”

“…For this reason, researchers are currently focusing on the development of cost-effective and "green" corrosion inhibitors with high efficiency. 1,7,8 In this context, the polymeric molecules having a high molecular weight and thus a greater surface coverage have proved to be promising corrosion inhibitors. Accordingly, carboxymethyl cellulose, Tapioca Starch, Gum Arabic and Chitosan have been reported as promising corrosion inhibitors.…”

“…17 The interesting ndings prompted us to perform the chemical functionalization of chitosan to improve the corrosion inhibition performance. Accordingly, thiosemicarbazide, thiocarbohydrazide and polyethylene glycol 1,8,19 were used to prepare chemically modied chitosan which was studied as the corrosion inhibitor for carbon steel in acid solutions. Further, we rstly reported the microwave-assisted synthesis of chitosan Schiff bases and used them as inhibitors against carbon steel corrosion in 1 M HCl.…”

Corrosion is a big challenge and many corrosion control methods have been adopted all over the world. It can damage the materials, which are used to construct automobiles, pipeline systems, bridges and buildings, petroleum refineries, etc. Corrosion inhibitors are used as effective alternatives for the protection of metallic surfaces against corrosion. Herein, the corrosion inhibition characteristics of 2-(4-сhlorophenyl)-1,4-benzothiazin-3-one (CBT) have been studied as efficient inhibitor for corrosion control of mild steel in 2.0 M phosphoric acid solution using potentiodynamic polarization, weight loss measurements and electrochemical impedance spectroscopy (EIS) techniques. The effects of inhibitor concentration on the inhibition action were investigated. The corrosion inhibition efficiency increased with the increase of CBT concentration up to 85% obtained at 25 °C at 5 mM concentration. The adsorption of CBT on metal surface obeyed Langmuir adsorption isotherm. Adsorption isotherm study suggests that both physical and chemical adsorptions may be the type of adsorption of the inhibitor on the metal surface. Polarization measurements showed that the CBT acted as mixed inhibitor. The surface morphology of mild steel, in the absence and presence of CBT in 2.0 M phosphoric acid solution, was studied using scanning electron microscopy (SEM). The SEM analysis strongly supports the results of electrochemical measurements.
