Ghazali, Syaidatul Atiqah (2017) Synthesis, characterization and anti-corrosion screening of Pt(II) thiacet azone complex / Syaidatul Atiqah Ghazali. [Student Project] (Unpublished)


A Pt(II) complex of thiacetazone, (TAC) ligand was successfully synthesized by slow diffusion method. The complex is obtained from the reaction of a few drop ammonia solution and thiacetazone. The ligand and synthesized complex was characterized by spectroscopic method such as FT-IR, UV-Vis, elemental analysis, molar conductance, gravimetric analysis and melting point, and have been applied as inhibitor. The results of characterization showed that TAC was coordinated in the N and S bidentate mode in the complex. The elemental analysis for compound were in a good agreement with the theoretical values. The value of melting point for complex which is 270-272 °C was higher than ligand which is 228-230 °C. The result of UV-Vis analysis revealed two types of transition which are π →π* and π →π* in ligand and complex spectrum. The molar conductance showed the Pt(II) complex is non-electrolyte with chemical formula [Pt(TAC)2]Ch. The gravimetric analysis presented the percentage of metal was 26.41 %. The data from corrosion inhibition study found that the inhibitor efficiency of ligand is higher than complex. The inhibitor efficiency increase as the inhibitor concentration increase from 0.001 M to 0.1 M.
