چکیده

The inhibitive effect of compound (1-acetyl-4, 5-dihydro-5-Bromophenyl-3-(thiophen-2yl) pyrazoles) on mild steel in 1M H2SO4 and 1M HCl was investigated by weight loss, Potentiodynamic polarization and electro chemical impidence studies. The synthesized compound of 1-acetyl-4, 5-dihydro-5-Bromophenyl-3-(thiophen-2yl) pyrazoles was characterized by FTIR, H NMR, C NMR and mass. The purity of the compound confirmed by TLC. The corrosion inhibition rate was increased with increasing the concentration of our synthesized inhibitor (1-acetyl-4, 5dihydro-5-Bromophenyl-3-(thiophen-2yl) pyrazoles). The synergetic effect also studied and observed good correlation between halides and our inhibitor. The adsorption isotherm was also confirmed by Langmuir adsorption isotherm.
