Corrosion Inhibition characteristics of Reinforced Steel in H2SO4 by benzoyl Thiourea

In The adsorption and corrosion inhibition performance of 3,3-diethyl(4-Chloro)benzoylthiourea, ClDEBT, at reinforced steel in H2SO4 interface was examined using gravimetric method 303.15 K. effectiveness ClDEBT improved by increasing the concentration. data on surface were fitted to Langmuir, Temkin thermodynamic–kinetic isotherms, some thermo-dynamics functions as α, y, f, ΔGads Kads obtained. Activation energies 35.69 55.99 kJ mol−1 for processes observed presence absence benzoylthiourea inhibitor, respectively. thiourea inhibitor found be spontaneous exothermic. Quantum parameters highest & lowest occupied molecular orbital energy (EHOMO) (ELUMO), gap (ΔE), determined correlated experimental data.
