Abstract

Mild steel plays an essential part in many construction industries due to its low cost and excellent mechanical properties. However, the use of strong acid in pickling, construction, and oil refining processes adds to a serious corrosion problem for mild steel. Two Cu(II) dithiocarbamate complexes were successfully synthesized, namely Cu[EtBenzdtc]2 and Cu[BuMedtc]2 by condensation to scrutinize the corrosion resistance activity toward mild steel in acidic media. The proposed structures of complexes were characterized using Fourier transform infrared (FTIR) and ultraviolet-visible (UV-Vis) spectroscopies. The melting point for Cu[EtBenzdtc]2 was found around 362–375 °C and 389–392 °C for Cu[BuMedtc]2. The percentages of Cu (II) found in Cu[EtBenzdtc]2 and Cu[BuMedtc]2 are 7.6% and 7.5%, respectively. Both complexes were non-electrolyte based on the molar conductivity analysis. Their corrosion inhibition performances were tested by a weight loss measurement. Cu[BuMedtc]2 showed a good result as a corrosion inhibitor compared to Cu[EtBenzdtc]2. The complexes showed good effectiveness in sulfuric acid (H2SO4) compared to hydrochloric acid (HCl) solution.
