Assessing the efficiency of danacid as corrosion inhibitor for aluminium in HCl medium: Experimental, theoretical and optimization studies.

The present study examined the corrosion protection of aluminium in 1M HCl by deploying expired danacid, with techniques such as gravimetric, electrochemical, and density functional theory (DFT). Inhibitor characterization was executed with Fourier transform infrared (FTIR) spectroscopy and gas chromatography mass spectrometry (GC-MS), which was supplemented by optimization of parameters with response surface methodology. The results of gravimetric study indicates that the inhibition efficiency (IE) rose with rise in danacid concentration and reduced with rise in temperature.

Testing the inhibition efficiency of the castor oil leaf as corrosion inhibitor of mild steel in HSO.

This study focused on the testing of castor oil leaf as corrosion inhibitor of mild steel in HSO. It involved the examination of the dynamics of molecular forces at the inhibitor and mild steel interface. Findings of the study will promote industrial diversification of castor oil leaf.
