The inhibition effect of new pyridazin namely ethyl (3-phenyl-6-thioxopyridazin-1(6H)-yl)acetate (GP3) on mild steel has been investigated using weight loss measurements in 1.0 M HCl at 30 - 50°C. The adsorption of this inhibitor was well described by the Langmuir adsorption isotherm and the adsorption isotherm parameters (Kads,
