Comparative Investigation of Thermodynamic Parameters of Seafood Waste as an Inhibitor for Mild Steel Corrosion in Varied Acidic Concentration

Mild steel (MS) is the material that frequently used in various sectors because of its specific properties like ductility and malleability, however it corrodes readily when exposed to corrosive environments. Inhibition best method prevent corrosion, since may be adjusted or added place without interrupting a process. The present study focused on thermal behavior Crab Shell extract (CSE) as corrosion inhibitor surface MS 0.5M 1M sulphuric acid medium. Temperature was employed test inhibitory action using weight loss measurement. effectiveness inhibition declines with rise temperature. In H2SO4 at 303K, maximum efficiency observed. nature adsorption both acidic medium follows El-Awady isotherm. activation thermodynamic revealed reaction spontaneous nature. process endothermic which confirmed by positive enthalpy values.
