In the realm of materials science and corrosion mitigation, the utilization of inhibitors has garnered substantial attention for safeguarding metal assets.This research delves into the proficient utilization of 4-phenyl-1-(phenylsulfonyl)-3-thiosemicarbazide (PP-3-T) as a corrosion inhibitor for mild steel in hydrochloric acid (HCl) solutions, as evaluated through weight loss measurements.The investigation reveals that the incorporation of PP-3-T into the HCl medium engenders a significant enhancement in the corrosion resistance of mild steel, attributed to the formation of a protective barrier via PP-3-T molecule adsorption.A notable finding of this study is the independence of the corrosion inhibition efficiency on variables such as PP-3-T concentration, immersion time, and temperature.The best inhibition efficiency of 96.1% for mild steel immersed in 1 M HCl solution is achieved in the presence of 0.5 mM PP-3-T.Furthermore, the inhibitory effect diminishes significantly as immersion time is extended from 10 to 48 hours at a constant PP-3-T concentration, highlighting the time-sensitive nature of the inhibition process.Alterations in temperature within the range of 303 to 333 K exhibit negligible impact on inhibition efficiency,
